C=25m+75
this is simple y=mx+b (slope intercept form) b is the constant, or 75, no matter what it stays the same. m is the factor that changes, it depends on how many months yous stay with the gym.

The formula for volume is l x w x h.
To find the missing link, we do the equation backwards.
l x 2.5 x 5 = 75
If we divide 75 by 5 then by 2.5, we get 6 which becomes our length.
To check, do 5 x 2.5 x 6 which should equal 75
6 is your length
well, one quarter of a year is 3 months, so at the end of third quarter, 9 months have passed, and since a year has 12 months, 9 months are simply 9/12 of a year.
<u>Answer: 5</u>
<u>explanation</u>:
x -5 apples = x^2 - 25
1 apple = x
cross multiply:
x (x-5) = 1 (x^2 - 25)
x^2 - 5x = x^2 - 25
the "X^2" WILL CANCEL OUT
-5x = -25
x = -25/-5
x = 5
