Question

M + 64 ≥ 80 = ?
m = ?

Answer 1

Well, little m is not the same as big M.

I will solve for big M.

M + 64 ≥ 80

M ≥ 80 - 64

M ≥ 16

What does M ≥ 16 mean?

You gotta know what the answer means. Otherwise math is dull.

It means that when the value of M is 16 or greater than 16, the original inequality is a true statement. Understand?

Answer 2

16

Explanation:

16+64 ≥ 80=true
