14 is a solution.
Hope this helps
Answer:
C(t) = I/F [1 - e^(-Ft/V) ] + C₀e^(-Ft/V)
as t = 0 ; C(t) = 1/F
Explanation:
dC/dt) = (-F/V)*C+(I/V)
To make it easier to solve, let
Constants: I, V,F
Variables: C, t

Answer:
Get the miles traveled from the trip odometer, or subtract the original odometer reading from the new one.
Divide the miles traveled by the amount of gallons it took to refill the tank. The result will be your car's average miles per gallon yield for that driving period.
Step-by-step explanation:

3x + 4y = 12
To find x subtract 4y from both sides
3x = 12 - 4y
Then divide all terms by 3
3x/3 = 12/3 - 4y /3
So, x = 4 - 4/3y
