Answer:
X = 2
Y=7
Step-by-step explanation:
The explanation is in the pictures
Answer:
x=2, y = 7.
As an ordered pair the solution is (2, 7).
Step-by-step explanation:
5x - 6y = -32
3x + 6y = 48
Adding the 2 equations, we eliminate the terms in y:
8x +0 = 16
x = 16/8 = 2.
Now substitute x = 2 in the first equation:
5(2) - 6y = -32
10 + 32 = 6y
6y = 42
y = 7.

Divide 20x^4 by 10x^2
Answer:
The answer for this equation is 2x⁶.
Step-by-step explanation:
In order to solve the equation, you have to Take out the Constants.
[tex] \frac{20}{10} {x}^{4} {x}^{2} [/tex]
Now you have to Simplify 20/10 to 2 because 10 divided by 20 is 2.
[tex] {2x}^{4} {x}^{2} [/tex]
And now you have to Use the product rule:
[tex] {x}^{a} {x}^{b} = {x}^{a + b} [/tex]
[tex]2x ^{4 + 2} [/tex]
and lastly, you have to simplify 4 + 2 to 6.
[tex] {2x}^{6} [/tex]
Therefor, the answer for this equation is 2x⁶.

can someone double check this? I got 12 as my answer
Answer:
angle C = 69 degrees
Step-by-step explanation:
(6x - 9) + (6x - 24) + (81 - x) = 180
11x + 48 = 180
11x = 132
x = 12
(81 - 12) = 69 degrees
Answer:
69°
Step-by-step explanation:
All angles in a triangle must add to 180°:
(5x+9)+(4x+15)+(x+36)=180
10x+60=180
10x=120
x=12°
The problem asks for the measure of angle C:
C=(81-x)°=69°
You were on the right track because you got the value of x correct. You just didn't answer the problem correctly.

Rodrigo buys a jacket that is on sale for 1/4 off the original price of 80$.he has a coupon for an additional 10% off.how much does Rodrigo pay for the jacket
Answer:
Price after off =80- 1/4 * 80 = 80-20 = $60
Coupon discount = 60*10/100 = $6
So, he have to pay, 60-6 = $54
Pedro wants to walk from the historic village to the science center. Then he will walk from the science center to the museum. If he walks at the speed of 2 7/10 how many hours will it take him?
Answer:
5 hours
Step-by-step explanation:
Speed = 2 7/ 10 miles per hour
From the chart attached :
Distance between historic village and science center : (-4 1/2, 5 1/4) to (-4 1/2, -1 3/4)
Taking the sum of the absolute value of the y coordinate :
|5 1/4| + |-1 3/4| = 5 + 1 + 1/4 + 3/4 = 7
From science center to museum :
(-4 1/2, - 1 3/4) to (2, - 1 3/4)
Taking the sum of the absolute value of the x coordinate :
|4 1/2| + |2| = 4 + 2 + 1/2 = 6 1/2
Total distance traveled = 7 + 61/2 = 13 1/2 miles
Time taken = Distance / speed
Time taken = 13 1/2 ÷ 2 7/10
Time taken = 27/2 * 10/27
Time taken = 10/2
Time taken = 5 hours

Answer:
∠AOB = 112°
Step-by-step explanation:
mentally draw line segment OC
that line bisects 124° so ∠OCB = 1/2(124°) = 62°
ΔOCB is isosceles because OB = OC
∠OBC = 62° because it is equal to ∠OCB
all triangle interior angles add up to 180°
∠BOC = 180° - 62° - 62° = 56°
∠AOC = 56° because OC was a bisector of ∠AOB
∠AOB = 56° + 56° = 112°

Imagine you are starting an office supply business. Your overall costs for supplies are $100. You plan on selling binders for $4 each and pencils for $2 each. Let x represent the number of binders sold and y represent the number of pencils sold.
Complete question :
Imagine you are starting an office supply business. Your overall costs for supplies are $100. You plan on selling binders for $4 each and pencils for $2 each. Let x represent the number of binders sold and y represent the number of pencils sold. Give an expression for the profit made.
Answer:
(2y + 4x) - $100
Step-by-step explanation:
Given that:
Cost of supply = $100
Supplies :
binders, sales price = $4
Pencils, sales price = $2
Number of binders sold = x
Number of pencils sold = y
The revenue from sale :
(Cost of pencils * number of pencils) + (cost of binders * number of binders)
Revenue = 2y + 4x
Profit, p = Revenue - Cost of supply
p = (2y + 4x) - $100
The City of Killeen utilities charges for water usage per gallon on a monthly basis as listed below.
Up to 500 gallons ($0.15/gallon)
More than 500 gallons - 1000 gallons ($0.33/gallon)
How much will Mrs Lapid pay if she uses 795 gallons in a particular month?
Answer:
$172.35
Step-by-step explanation:
The computation of the amount need to pay for 795 gallons is shown below
Up to 500 gallons it charges $0.15 per gallon
And, for more than 500 gallons till 1000 gallon, it charges $0.33 per gallon
So for 795 gallon, the total amount would be
= 500 × $0.15 - (795 - 500) × $0.33
= $75 + $97.35
= $172.35

Milk that has been boiled and then covered keeps longer than fresh milk. explain
Answer: Its also okay for drinking after boiled
Step-by-step explanation:
According to the Department of Food Science in Cornell University, pasteurised or boiled milk has a longer shelf life than raw milk, contrary to the myth that boiling milk will not reduce its lactose content.
Answer:
Milk that has been boiled and then covered keeps longer than fresh milk because the milk is absorbing the heat and when it is covered it will not be spoiled.

A baker recorded the number of batches of
cookies he made on each of seven days. He

The baker baked 20 batches of cookies on the
eighth day. He redraws the box-and-whisker plot
to include his data. Which statement comparing
the new box-and-whisker plot to the original box-
and-whisker plot is NOT true?
A. The median increased.
B. The lower extreme increased.
C. The upper extreme increased.
D. The value of the interquartile range
increased
Answer:
B. The lower extreme increased.
Step-by-step explanation:
From the original box and whisker plot, the lower extreme (minimum) is 5 ; The upper extreme, maximum is 15.
The number of batches baked on the eight day is 20. This exceeds tbe previous maximum value. Hence, upper extreme( maximum) value of the new plot will change from 15 to 20.
The lower extreme isn't affected as the obtained value isn't below 5.
The median value will Increase and the upper quartile value will also increase. Once the upper quartile value increases, the interquartile range will also increase

Find an explicit formula for the arithmetic sequence -5, 13, 31,
49,....
Note: the first term should be b(1).
B(n)=(blank)
Answer:
b(n) = -23 + 18n
Step-by-step explanation:
NOTE - This is an arithmetic sequence, so each number is increasing by addition. If you were in a geometric sequence, however, you'd be multiplying. This means that the explicit formula for the geometric sequence you'll be learning later on will be different.
The formula for explicit formula is b(n)=b(1)+d(n-1). The variable d represents the common difference and the a is whatever number of the term you are using.
Since you have b(1), you look at what your first term is. Plug -5 into a(1).
To find your common difference, find 13-(-5). This is 18, and adding it to the others you can see that it continues.
So, plugging in what you have so far it looks like b(n) = -5 + 18(n - 1)
All we need to do now is simplify.
1. Distribute: -5 + 18n - 18
2. Add like terms: -23 + 18n
