Multiply both numbers by 4.
It takes you 360 minutes to wash 3 of your windows.
Divide both numbers by 3.
It takes you 120 minutes to wash 1 of your windows.
120 minutes = 2 hours.
It will take you 2 hours to wash all the windows.

Step-by-step explanation:
C = 16 * 3 = 48
My guess is 30 for the sample size.
10 times the sum of 2 and 1 is represented by the following expression:
10 x (2 + 1)
10 x is ten times, and (2 + 1) the sum of 2 and 1, "10 times the sum of 2 and 1".
Answer: <em>x/2 - 10 = 27, and x is the number. </em>
I think that's right. :)
The answer is f ⁻¹(x) = ½x - ³/₂
