Write an inequality for the sentence. Then solve the inequality. Fifteen less than a number is at most 6.
The inequality is:
x - 15 ≤ 6
To solve for x, we will add 15 to both sides:
x - 15 + 15 ≤ 6 + 15
Simplifying:
x ≤ 21
Therefore, any number that is less than or equal to 21 will satisfy the inequality "Fifteen less than a number is at most 6."
