Answer:
11
Step-by-step explanation:
All angles on a triangle equal 180. 80+60=140.
Now to solve for x, we set it to equal 40 for 180-140.
40=3x+7. 40-7=33
33=3x 33/3=11
x=11
4>-3
-2>-5
1=1
They want to make sure you understand inequalities and know how to use the inequality signs.
I would round them so it would be 500 divided by 20
The answer should be close to 25
