Q. Solve for w.10≤w+18≤20Write your answer as a compound inequality with integers.Choices:(A) 28≤w≤38(B) −8≤w≤38(C) −8≤w≤2(D) 28≤w≤2
Subtract 18 from inequality: To isolate w, we need to subtract 18 from all parts of the inequality because w+18 involves adding 18 to w.10≤w+18≤2010−18≤w+18−18≤20−18−8≤w≤2
