Answer:
20
Step-by-step explanation:
75% of 20 = 15
I believe this is correct and hope it helps :)
Suppose the length is 7x, the width is then 3x
7x*3x=525
21x²=525
x²=25
x=5
so the length is 7*5=35, and the width is 3*5=15
3x + 40 + x = 180
-40. -40
——————————-
4x. 140
—. ——-
4. 4
x = 35
The absolute value of B is 1 3/5 because although B is in the negatives, absolute value makes it positive.
