Choose the inequality that could be used to solve the following problem. three times a number is at most negative six. a. 3x ≤ -6 b. 3x < -6 c. 3x ≥ -6 d. 3x > -6

The answer is A. 3x ≤ -6.

Three times a number is 3x. Negative six is -6. But, how to solve the inequality?
At most -6 means that 3x can be -6 or less. If it was said at least -6, that it would mean that 3x can be -6 or more.
So, three times a number is at most negative six can be expressed as:
3x ≤ -6

1.3 and 1 1/3 are both closest to 1. hope this ; )
