PLEASE SIMPLIFY AND SHOW YOUR WORK!
Answer:
2(19[tex]x[/tex]x -11)
0R
38x - 22
Step-by-step explanation:
QESTION: 18x – 4(9 – 5x) + 14
Rearrange terms that whould be -: 18x – 4(-5x + 9) + 14
Disterbot the one in brakect and the nagative four: – 4(-5x + 9)
SLOVE: – 4(-5x + 9) ^^ 4 x 5 = 20 and 4 x 9 = 36 ^^ PUT THE ALL TOGETHER.
What you have now --> 18x + 20x - 36 + 14
Now, it's time to use your PEMDAS, we have Add and Subtract so you are going to do A fisrt (Add).
-36 + 14 = -22
Now you have, 18x + 20x - 22
Combine the like terms: 18x + 20x = 38x (don't forget the - 22)
38x - 22
2 x 19 = 38
2 x 11 = 22
What do you notice? ------- They all have 2 right? YES!, So put 2 in the front with parentheses, then put 19x and -11 in the parentheses.
Here is your EQUATION!
2(19[tex]x[/tex] -11)

When a number is decreased by 7.5%, the result is 61. What is the original number to the nearest tenth?
Answer: It's 65.9
Step-by-step explanation:
decreased by 7.5%means 100% - 7.5% = 92.5%92.5% * x = 61x= 61 / 92.5%x = 65.9459to the nearest tenth :original number is 65.9Hope this helps have a awesome day/night❤️✨Find the value of x in this figure
Can you please for the love of god help me it's 2am and I cannot figure this out
Answer:
8:05 pm (If you round to the nearest tenth place)
Step-by-step explanation:
basically, 4:00 pm and 5:10 pm have a 1 hour and 10 minute difference.
1 hour and 10 minutes divided by 65 miles is 1.6923076 or 1.7 minutes
1.7 minutes times 150 miles is 2 hours and 55 minuets
2 hours and 55 minutes plus 5:10pm is 8:05 pm
I'm so sorry if I'm wrong!
Answer: a) d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65 b: 6:41 pm
duration of time passed:
5:10 pm - 4:00 pm = 70 mins
distance = 65 miles
you points to use to make an equation:
(0,0) and (70,65) ---------------------> ( (0,0) is bc youre beginning the trip and you have no distance )
find the slope of your "future" equation
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{65}{70}[/tex] = [tex]\frac{13}{14}[/tex] = m
now use point-slope form
y - 65 = [tex]\frac{13}{14}[/tex] (x - 70)
y= [tex]\frac{13}{14}[/tex] (x - 70) + 65
and since it wants it in terms of d and t,
d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65
part b:
150 = [tex]\frac{13}{14}[/tex] (t - 70) + 65
85 = [tex]\frac{13}{14}[/tex] (t - 70)
85 = [tex]\frac{13}{14}[/tex] t - 65
150 = [tex]\frac{13}{14}[/tex] t
2100 = 13t
161.54 = t
about 162 minutes
Thennnn:
162/60 = 2 hours and 41 mins
4:00 pm + 2 hours and 41 mins = 6:41 pm

Fine two integers that have a sum of -17 and a product of 52. What are the integers?
Answer:
{4, 13}
Step-by-step explanation:
Represent the integers by I and J. Then I + J = -17 and I*J = 52.
Let's solve this system using substitution. Solve the first equation for I as follows:
I + J = -17 becomes I = -J - 17
Substitute -J -17 for I in the second equation:
(-J - 17)*J = 52
Performing the indicated multiplication, we get:
-J^2 - 17J - 52 = 0
Let's solve this using the quadratic formula. The quadratic coefficients here are {-1, -17, -52}, and so the discriminant, b^2 - 4ac, is
(-17)^2 - 4(-1)(-52), or 289 - 208, or 81. This result is positive, so we know that the quadratic equation has two real, unequal roots. They are:
17 ± √81 17 ± 9
J = --------------- = ---------------
2(-1) -2
Evaluating this last result, we get J = (17 + 9)/2, or J = 13, and
J = (17 - 9)/2 = 8/2, or J = 4

Answer:
422[tex]cm^2[/tex]
Step-by-step explanation:
1. Approach
This problem asks one to find the surface area of the given figure. This can be done by splitting the given figure into two similar figures. Then calculate the surface area of each of the similar figures. After doing so, subtract the covered surface areas, the contact point between the two simple figures is not a part of the surface area since it is covered by the other part of the figure. Remember to take away twice the area of this contact point, since it is present on both figures.
2.Find the surface area of the first figure
The surface area of a figure is the two-dimensional space around the figure. In essence, if one were to wrap the figure in paper, the surface area is the amount of paper one would need. Find the 2-dimensional area of each side, this can be done by multiplying all combinations of two dimensions together, adding the results, and then multiplying that value by (2).
(5) * (10) = (50)
(5) * (7) = (35)
(7) * (10) = (70)
Now add thee value together,
(50) + (35) + (70)
= (155)
Double the result,
(155) * (2) = (310)
3. Find the surface area of the other figure
Now repeat the process that was used to find the surface area of the other figure for this figure.
(8) * (4) = (32)
(4) * (3) = (12)
(8) * (3) = (24)
Add the results,
(32) + (12) + (24) = (68)
Double the value,
(68) * (2) = (136)
3. Now subtract the repeated side
Now that one has the value of both simple figures, add up the value and then subtract twice the value of the repeated side.
(310) + (136) = (446)
(446) - ((2)*(4)*(3))
= (446) - (24)
= (422)

Brad put 10 crickets in his pets lizard cage. After one day, Brad's lizard had eaten 50% of the crickets he had put in the cage. By the end of the next day, the lizard had eaten 20% of the remaining crickets. How many crickets were left in the cage at the end of the second day?
Answer:
There are 4 crickets left
Step-by-step explanation:
10/2=5
20% of 5 is 1
5-1=4
Don't forget to brainliest me
Answer:
4 crickets
Step-by-step explanation:
On the first day, the lizard ate 50% of the 10 crickets it was given. 50% of 10 is 5 (10 times 0.5), so five crickets remain. The next day, the lizard ate 20% of the 5 remaining crickets. 20% of 5 is 1 (5 times 0.2), and 5-1=4, so 4 crickets are left.

Two neighbors in a rural area want to know the distance between their homes in miles. Help 'em out! 1 mile = 5,280 feet. Find the distance between their houses in miles. (i have 69 points left so PLEASE PLEASE dont be rude and answer like this ¨ssieoiej¨)
Answer:
4/5 OR 0.8
Step-by-step explanation:
Divide the distance between them by 5,280. You should then get a decimal of 0.8. Not sure if you are looking for decimal or fraction, but 0.8 as a fraction is 4/5. So 4/5 of a mile is in between their two houses. Hope this helps :)

The width of a rectangle is 4n - 1.5 feet and the length is 1.5n + 4 feet. Find the perimeter of the rectangle. The perimeter of the rectangle is feet.
(Simplify your answer. Use integers or decinals for any numbers in the expression.)
Answer:
11n + 5
Step-by-step explanation:
First, what is the perimeter of a rectangle referring to? It's referring to the outside surrounding the rectangle. You just need to know that the formula for a rectangular perimeter is:
2(L+W) (W = width, L = length)
We are given width: 4n - 1.5We are given length: 1.5n + 4Now substitute those values for the formula.
2 (4n-1.5 + 1.5n + 4)2 (5.5n + 2.5)11n + 5can you please show me how you do this problem im having trouble with it thanks!

All measures of central tendency must appear as a number in the set of data collected.
Which student’s statement is CORRECT?
A.
Zeke says this is never true because all the measures of central tendency are never numbers in the set of data.
B.
Emily says this is always true because all the measures of central tendency also have to be numbers in the set of data.
C.
Harry says this is sometimes true because the mean and median may or may not be in the set of data, but the mode is always in the set of data.
D.
Brook says this is sometimes true because the mean and mode may or may not be in the set of data, but the median is always in the set of data.
