Answer:20 pieces
Step-by-step explanation:
8 7/8=71/8
71/8 *4/7(reciprocal of 1 3/4)= 284/56= 20.2867
I would probably have to go with 62.5
The first question deals with an exponent: so your equation is likely something like this: (assuming x equals the number of feet) πx², which can also be explained as pi x squared.
5x + y = 2
4x + y = 4
5x + y = 2
-(4x + y = 4)
5x + y = 2
-4x - y = -4
x = -2
x = -2
5x + y = 2
5(-2) + y = 2
-10 + y = 2
y = 2 + 10
y = 12
x = - 2
4x + y = 4
4(-2) + y = 4
-8 + y = 4
y = 4 + 8
y = 12
x = -2 ; y = 12 ⇒ (-2,12)
