The number of DVD's sold at Fry's Electronics in a month was 920 and the number of DVD's sold decreased by 12 per month. The number of Blu-ray discs sold at Fry's Electronics in the same month was 502 and the number of Blu-ray discs sold increased by 26 per month. Write a system of equations to model th situation. If this trend continues, in how many months will the number of DVD's sold each month equal the number of Blu-ray discs sold each month? How many each disc is sold in that month?
Answer:
a) 11 months
b) 788 discs
Step-by-step explanation:
Let us represent number of months = x
For DVD's
The number of DVD's sold at Fry's Electronics in a month was 920 and the number of DVD's sold decreased by 12 per month.
Hence:
920 - 12x
For Blu ray
The number of Blu-ray discs sold at Fry's Electronics in the same month was 502 and the number of Blu-ray discs sold increased by 26 per month.
502 + 26x
Write a system of equations to model th situation.
a).If this trend continues, in how many months will the number of DVD's sold each month equal the number of Blu-ray discs sold each month?
To solve this:
DVD's = Blu-ray
920 - 12x = 502 + 26x
Collect like terms
920 - 502 = 26x + 12x
418 = 38x
x = 418/38
x = 11 months
b) How many each disc is sold in that month?
For DVD's
920 - 12x
x = 11
Hence:
920 - 12 × 11
= 920 - 132
= 788 discs
For Blu ray
= 502 + 26x
x = 11
Hence:
= 502 + 26x
= 502 + 26 × 11
= 788 discs
Therefore, 788 discs were sold in each month

Shelly is putting a child safety fence around the edge of her swimming pool. If the company charges $15 per foot, how much will she pay?
If the company charges $15 per foot then she will pay $1,110.
What is Perimeter?The perimeter of a form is the space surrounding its edge. We must sum up the lengths of the rectangle's four sides in order to get its perimeter.
We have Pool in the shape of Trapezium whose dimensions are
Base 1 = 25 feet
Base 2 = 17 feet
Non parallel side = 16 feet
So, the perimeter of pool
= 25 + 17 + 16 + 16
= 74 foot
Now, the charge per foot is $15.
So, the total charges are
= 74 x 15
= $1,110

Find the slope and y-intercept of equation 19x - 4y = 7
Answer:
Slope: 19/4
y-intercept: 1.75
Step-by-step explanation:
19x-4y=7
To find the slope and y-intercept, change the order of the equation to put it in y-intercept form. (y-intercept form: y=mx+b). Where m equals slope and b is the y-intercept.
In order to do this, Subtract 19x from both sides of the equation to equal:
-4y=7-19xThis equation can also equal out to:
-4y=-19x+7Now, divide each side by -4
y=[tex]\frac{19}{4}[/tex]x-1.75This will mean that 19/4 is the slope and 1.75 is the y-intercept

Hello, So this is for school in general, I am in 7th grade and when i am given assignments i attempt to do them and i get confused, I try do them and i end up sticking with it. Then i don't pay attention and i get confused on current assignments then i get FARTHER behind and i get so far behind and pressured i shut down and give up, Any Suggestions to help because at 11:59 PM all assignments lock and 3rd marking period assignments will not be graded
Answer:
Try working in 15-30 minute periods and taking a 5 minute break between
don't stress about it because you can do this! just sit down in a quiet room and try your best your only in 7th grade so even if you don't get everything done it won't effect you moving forwards too much and try talking to someone about falling behind like a trusted adult or teacher they might be able to help you come up with a game plan for the future
Hope This Helps And I Wish You Luck!
Answer:
Hmm similarly my sister and I, who are both in school, have the same issue. Some tips that I use myself are, listening to music without words in the background. This helps me calm down and releases stresses, as well as calming scents if you have any like lavender. Try to stretch every so often, this helps gain energy and let blood flow through your veins to your brain. Try listing your assignments you need to get done for the week and when you get done with one, cross it out. This makes me feel so much more accomplished and then I can tackle the assingments I am behind on. Also drink LOTS of water! This helps your WHOLE body!
Remember that these don't work for everyone and if you need anything else I can try to give you some more help! Try not to stress too much, believe me that is definitely a lot easier said than done! As long as you try your best and work towards your goal, that's what matters. Life is about your journey, not your destination. Try to stay positive! Not everything is going to be easy, but you can do it!
Step-by-step explanation:
in 2010, the price of a laser printer was $1599. in 2018, the price of the same type of printer had dropped to $579. find the percent of decrease. round to the nearest percent
Hi there!
nearest percentage=64%
1.Subtract starting value and final value:
[tex]1599-579=1020[/tex]
2.Divide it by the starting value:
[tex]1020*1599= 0.6378986866791744840525328330206378986[/tex]
3.Multiply the term by 100:
[tex]0.6378986866791744840525328330206378986[/tex]·[tex]100= 63.78986866791744840525328330206378986[/tex]
4.Round the term:
[tex]63.78986866791744840525328330206378986=64[/tex]
Therefore, the decrease of the total 8 years was 64%.
Answer:
64%
Step-by-step explanation:
579 is a 63.789868667917% decrease of 1599.
Percentage of decrease = |1599 - 579|/1599 = 1020/1599 = 0.63789868667917 = 63.789868667917%

Oreos 2.98 for 15.5.Oz or chips ahoy for 2.50 for 14.Oz I pick chips ahoy BUT ITS ASKING UNIT RATE CENTS PER OZ
Answer:
Unit rate of oreos = 19.23 cents/oz
Unit rate of Chips Ahoy = 17.86 cents/oz
The cheapest and most affordable is the chips ahoy because it has a lower unit rate.
Step-by-step explanation:
Oreos 2.98 for 15.5.Oz or chips ahoy for 2.50 for 14.Oz I pick chips ahoy BUT ITS ASKING UNIT RATE CENTS PER OZ
We would be finding the Unit Rate of each product.
For Oreos
Oreos $2.98 for 15.5.Oz
We convert dollars to cents
1 dollars = 100 cents
2.98 dollars = x
x = 2.98 × 100 cents
= 298 cents
Hence, the unit rate in cents/oz
= 298 cents/15.5 oz
= 19.225806452 cents/oz
= 19.23 cents/oz
For Chips ahoy
$2.50 for 14.Oz
We convert dollars to cents
1 dollars = 100 cents
2.50 dollars = x
x = 2.50 × 100 cents
= 250 cents
Hence, the unit rate in cents/oz
= 250 cents/14 oz
= 17.857142857 cents/oz
= 17.86 cents/oz
Therefore, the cheapest and most affordable is the chips ahoy because it has a lower units rate.

Step-by-step explanation: The earliest fractions were reciprocals of integers: ancient symbols representing one part of two, one part of three, one part of four, and so on.[28] The Egyptians used Egyptian fractions c. 1000 BC. About 4000 years ago, Egyptians divided with fractions using slightly different methods. They used least common multiples with unit fractions. Their methods gave the same answer as modern methods.[29] The Egyptians also had a different notation for dyadic fractions in the Akhmim Wooden Tablet and several Rhind Mathematical Papyrus problems.[citation needed]
The Greeks used unit fractions and (later) continued fractions. Followers of the Greek philosopher Pythagoras (c. 530 BC) discovered that the square root of two cannot be expressed as a fraction of integers. (This is commonly though probably erroneously ascribed to Hippasus of Metapontum, who is said to have been executed for revealing this fact.) In 150 BC Jain mathematicians in India wrote the "Sthananga Sutra", which contains work on the theory of numbers, arithmetical operations, and operations with fractions.
A modern expression of fractions known as bhinnarasi seems to have originated in India in the work of Aryabhatta (c. AD 500), Brahmagupta (c. 628), and Bhaskara (c. 1150). Their works form fractions by placing the numerators (Sanskrit: amsa) over the denominators (cheda), but without a bar between them. In Sanskrit literature, fractions were always expressed as an addition to or subtraction from an integer. The integer was written on one line and the fraction in its two parts on the next line. If the fraction was marked by a small circle or cross, it is subtracted from the integer; if no such sign appears, it is understood to be added.
what is two numbers that add to 20 and the difference is 6
13 and 7.
Steps
x + x = 20
x - x = 6
2x = 26
x = 13
x = 20 - 13
x = 7
Answer:
13 and 7
Step-by-step explanation:
We have two unknown numbers that add up to 20 and subtract to 6. The question is asking us to find out these two hidden numbers.
Let's form two equations.
x + y = 20
and
x - y = 6
Since we have a positive y and negative y, we can use the addition method to these systems of equations.
x + y = 20
x - y = 6
+-----------------
2x = 26
Now isolate x to get x.
Divide both sides by 2 :
x = 13
Now that we have x, we can plug it into the equations.
13 + y = 20
13 - y = 20
So what number will make this true. Use the backwards method :
20 - 13 = 7
Therefore, 13 and 7 are our two numbers.

Answer: X = -4
Step-by-step explanation:
90 - 5x + 62 -2x = 180
152 - 7x = 180
-7x = 28
x = -4
Check your answer by pluging in the vaule of x
90 - 5(-4)
90 + 20 = 110
62 - 2(-4)
62 + 8 = 70
110 + 70 = 180
Checks out.
Answer: 110 degrees and 70 degrees
Step-by-step explanation:
These angles are same side (of the traversal line) interior (inside the parallel lines) angles. Same side interior angles sum to 180 degrees. Add the two angles together and set them equal to 180. (90-5x) + (62-2x) = 180
Combine like terms. 90+62= 152 and -5x + -2x = -7x rewrite the equation as 152 + -7x = 180
Subtract 152 from both sides of the equation.
-7x = 28. Now isolate x by dividing both sides by -7. X= -4. Now we can substitute -4 back into the original equations. 90 -5(-4) = 90 +20 = 110 and 62 - 2(-4) = 62 + 8 = 70
We can double check our work to see if these two indeed add up to 180. 110 + 70 = 180

The surface area of the cuboid box is S = 126 cm²
What is the surface area of cuboid?
A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges
The total surface area of the cuboid is given by the formula
Surface Area = 2 ( LH + LW + HW )
where ,
Length of the cuboid = L
Width of the cuboid = W
Height of the cuboid = H
Given data ,
Let the surface area of cuboid be S
Length of the cuboid = L = 6 cm
Width of the cuboid = W = 5 cm
Height of the cuboid = H = 3 cm
