Answer:
r = -4
Step-by-step explanation:
2r + 7 = - 1
2r = - 1 - 7
2r = - 8
12.5% = .125
32 x .125 = 4
32 + 4 = $36
Known facts:
A line shaft rotating at 250 rpm, a grinder shaft that turns at 1200 rpm diameter of grinder pulley is 5 inches.
1. Proportion equation
350/1200 = 5/x
2. Cross multiply
1200*5=250*x
x=(1200*5)/250 = (24*50*5)/(5*50) = 24
