If you divide or multiply both sides of an inequality by a positive number, you do not flip the direction of the sign.
In your case, divide both sides by 4 and you get
-22.5 > T
which can also be written
T < -22.5
(I left out the underline because I am too lazy to look up how to type it with ALT+ keys).
Thank you.. do you happen to know how I would graph this?
on a numberline?
Only the parts of the line to the left of -22.5 are solutions. Maybe they want you to show a heavier line there; I don't know the recommended graphical rules in your case.
