Write an inequality for the sentence. Then solve the inequality.

Question

Fifteen less than a number is at most 6
X + 15 <_ 6; x <_ -9
X - 15 <_ 6; x <_ 21
X - 15 >_ 6; x >_ 21
X - 15 >_ 6; x >_ 16

Answer 1

The correct inequality is X - 15 <= 6.

To solve:
X - 15 <= 6
Add 15 to both sides:
X <= 21

So the solution is x is less than or equal to 21.
