2x - 2y = -12
- 2y = -2x - 12
y = x + 6

4x - 7 (x + 6) = -15
4x - 7x - 42 = -15
-3x - 42 = -15
-3x = 27
x = -9

y = -9 + 6
y = -3

(-9 , -3) is the solution

Help me asap please!!!

Well, just by looking at the beginning of the problem, Jamelia had made the common mistake of thinking that 
\sqrt{72} (<span>8.4852...)
</span>is equal to 
2* \sqrt{36} (12)

If you want to estimate a square root like 72, simply find squares that would fit around the number you are looking to find, in our case, 72.

So 9*9 is 81, which is too high and 8*8 is 64, which is too low. So you know that somewhere between those numbers is what your root of 72 is!

Sarah's craft project uses pieces of yarn that are 1/8 yard long. She has a piece of yarn that is 3 yards long. How many 1/8 yar
Verdich [7]
If she used all of her yarn, she'd have 24 pieces. If she wanted 1.25 left, she'd have ten less because 24 • .125 = 8, and 1/4 of eight = 2, and 2 + 8 = 10.

So she'd have 14 pieces.
