Answer:
Multiply the rate per hour by the number of hours (n) and add the deposit.
A)
Bike shop x: c = 2.75n + 3.00
Bike shop z: c = 1.75n + 7.00
B) to find when they will cost the same set the equations equal to each other and solve for n:
2.75n + 3.00 = 1.75n + 7.00
Subtract 3 from each side:
2.75n = 1.75n + 4.00
Subtract 1.75n from both sides:
1.00n = 4.00
Divide both sides by 1:
n = 4 hours
Answer:
-9.85
Step-by-step explanation:

Determine the volume
The volume of a cylinder is calculated as thus:
Substitute values for r and h
<em>Hence, the volume of the cylinder is 18312.48mm³</em>
Solve 10x = 4.1 for x. Divide both sides of this equation by 10: x = 4.1 / 10.
x = 0.41
