February has the colder average temperature. The larger the negative number is, the colder it is. This applies to temperature, not all situations.
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.
