Simplify:

7r + 10 - 2(2r + 3s - 5t) + 2(4s - t) + 5 *

3r+2s+8t+15

Step-by-step explanation:

After simplifying 7r+10-2(2r+3s-5t)+2(4s-t)+ 5, you will have 3r+2s+8t+15.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.
