Question

You do not need to flip the inequality sign when solving the inequality -3t + 7 ≥ 9.

True or False

Answer 1

True

Explanation:

Answer 2

You only need to flip the inequality if you multiply or divide the inequality by a negative number.

-3t + 7 ≥ 9

Subtract both sides by 7.

-3t + 7 - 7 ≥ 9 - 7
-3t ≥ 2

Divide both sides by -3.

-3t / -3 ≥ 2 / -3
t ≤ 2/-3

So, yes, you will need to flip around the inequality sign.
