13 x 11 = 143
14 x 12 = 168
168 + 143 = 311 people

For each of these problems, all you need to do is isolate the variable. I’ll do the first few to help you out :)

32) 7 = -12 + e
Add 12 to both sides to isolate e.
19 = e

35) (r + 4) + 2 = 1
Subtract 2 from both sides.
r + 4 = -1
Subtract 4 from both sides to isolate r.
r = -5

38) -2 + (1 + p) = 5
Add 2 to both sides.
1 + p = 7
Subtract 1 from both sides to isolate p.
p = 6.

So essentially, all you need to do is add and subtract from each side to isolate the variable given in each problem. :)

Extra tip: In order to get rid of a number on one side (to isolate a variable), you must perform the opposite operation. For example, -2 + x = 1. In order to isolate x, add 2 to the left side to get rid of it, as well as adding it onto the right side so that it is not erased completely to get x=3)

75 feet of PVC pipe for $111.50 OR 100 feet of PVC pipe for $135.25
kozerog [31]

Answer:

100 Feet of PVC for 135.25

Step-by-step explanation:

If you had 75 feet of PVC and paid 111.50 you would pay 1.48 a foot for each PVC but if you paid 135.25 for 100 feet you would pay 1.35 a foot which in turn would become cheaper.

Each unit on the grid stands for one miles determine two ways to calculate the distance from josie's house to annies
Novosadov [1.4K]
I encountered this problem before but it had an accompanying image and list of answer choices.

I'll attach the image and include the list of options. 

Each unit on the grid stands for one mile. Determine two ways to calculate the distance from Josie's house to Annie's house.
A) Distance Formula and Slope Formula
B) Midpoint Formula and Slope Formula
C) Distance Formula and Midpoint Formula
<span>D) Distance Formula and Pythagorean Theorem
</span>
My answer is: D.) Distance formula and Pythagorean Theorem.

When looking at the image, I can visualize a right triangle. I'll simply get the measure of the long and short legs and solve for the hypotenuse. 
Since the distance formula is derived from the Pythagorean theorem, it can be used to determine the distance from Josie's house to Annie's house.
