Divide both the top and bottom by 2 and you get 2/3
5. The answer is D
because it says no more than 160 so it's possible to be equal to 160.
6.
So the answer is A
I would go about solving this by elimination because the x variables are already the same so all you would have to do is change one equation to the opposite signs and add them, so it would look like:
7y + 5x = 19
+ -3y - 5x = -7
-------------------
4y=12
y=3
Hello! So, you use 120 pieces of fabric. You could not use all 120 pieces, because you can not make a square. The most you could use to make a square is 100. That would be 10 squares a row, with a side length of 6, which would make a perimeter of 60. Then, the other side would be 60. So 60 * 60 is 3600. The area of the blanket is 3600 square inches.
Your goal here is to determine the value of x.
Use the principle of similar triangles:
x is to 12 as 6 is to 8:
x 6
--- = ----
12 8
Therefore, 8x = 72, and x = 9 (answer)
