Answer:
245 miles driven.
Step-by-step explanation:
A car rental company charges $10 a day and 17 cents per mile to rent their cars. 17 cents = 0.17 dollars
Let x be the number of miles and y be the number of days
total change =0.17x + 10y
Given total change is 61.65 and number of days = 2
plug in the values and find out the number of miles
61.65 = 0.17 x + 2(10)
61.65 = 0.17 x + 20
subtract 20 on both sides
41.65 = 0.17x
Divide by 0.17 on both sides
x = 245
245 miles driven.
Answer:
f=(d-c)/g
Step-by-step explanation:
fg+c=d
fg=d-c
f=(d-c)/g
Answer:
8.3 L/s
Step-by-step explanation:
To find the answer you need to find the slope also known as the rate of change. When you find slope it is always change in y over change in x.

Then simplify

Then divide to get your slope/average rate of change
= 8.3
