There is an app called photo math I’m not sure if you have heard about it but it’s free. I’m not to good at math so I use it often. You should download it. You take a picture of the problem and it gives you step by step directions on how to solve each problem.
A (-9.5, -9.5) B (5.5,-2.5) C (3.5,3.5)
The answer is 8x.
You are combining like terms as 5 and 3 both have x so you are simply adding 5+3= 8
Your answer: -0.8
first you would add all of your temperatures together which would give you -5.6
then you would divide -5.6 by 7 because u have 7 numbers
which would give you your answer!
hope this helps, good luck!
