Question

Solve the inequlity 2s+5s+12=132 A. s=-30 B. s=40 C. s=120 D. s=9

Answer 1

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.
