Which inequality represents the following sentence?

Twelve fewer than a number is at least 18.

12 + x ≤ 18

x - 12 ≥ 18 (This one correct?)

12 - x ≥ 18

x - 12 < 18,

x - 12 ≥ 18 Let's break down the sentence and create an inequality from it. We'll use X to represent the number. "Twelve fewer than a number is at least 18." The "Twelve fewer than a number" indicates subtraction, so let's do that. X - 12 "is at least 18." would be a greater than or equal relationship. So we have X - 12 ≥ 18 And we're done. The desired equation is: x - 12 ≥ 18
