X*y=72
x = 5y-2
x=72/y
72/y=5y-2
72=5y^2-2y
5y^2 -2y - 72 = 0
(5y+18)(y-4)=0
y = -18/5 discard
or y = 4
4x=72
x=18
(18,4)
Answer:
-2.5
Step-by-step explanation:
Plugged into calculator
The total distance traveled by cycle = 50 * 12 = 600 inch

Total rotation = 600 / 150.72
= approx. 4
In short, Your Answer would be Option C
