Solve the inequlity 2s+5s+12=132

A. s=-30

B. s=40

C. s=120

D. s=9

First off, an inequality means that there is no equals sign ... it will be either greater than (>) or less than (<). So we'll solve yours with the assumption that it is supposed to be greater than ...

2s + 5s + 12 > 132

7s + 12 > 132

7s > 132 - 12

7s > 120

s > 120/7

s > 17 1/7

**If it was supposed to be less than instead of greater than, just change the sign. It doesn't affect the outcome.
