Answer:
777 fewer belts
Step-by-step explanation:
288/4 = 72
72 + 15 = 87
288*3 = 864
864 - 87 = 777
A) x = 0, 2
(x + 4) / 6x = 1 / x
this is a proportion, so you can cross-multiply and get:
x(x + 4) = 6x
x² + 4x = 6x
x² - 2x = 0
x(x - 2) = 0
x = 0
x - 2 = 0 so, x = 2
A. 2.50
25 ÷ 2 = 12.5
15 - 12.5 = 2.50
$1.37 (1.368333)
6 divided by 8.21
A(0,+3)
