Exercise 48 Page 289

What operations can you perform for the inequalities to match?

m-5≥ 12

Practice makes perfect
By comparing the inequality given in the exercise with the original inequality, we can see the difference between them. Original Inequality:& m+ 7 ≥ 24 Given Inequality:& m- 5 ≥ ?To make the solution easier to visualize, let's rewrite - 5 as a difference of 7 and another number. Given Inequality: m+7-12 & ≥ ? For the inequalities to match, we have to subtract 12 from both sides of the original inequality.
m+7≥ 24
m+7-12≥ 24-12
m-5≥ 12
