Answer:
x=5
Step-by-step explanation:
7 (x-8)=2x-31
Distribute the 7 to the x and -8 (basically multiple 7 with the x and -8)
7x-56=2x -31
Drag the 2x over to the other subtracting it from 7x.
7x-2x-56=-31
5x-56=-31
Drag the 56 to the other side and add it to -31
5x= -31+56 (or 56-31)
5x= 25
Divide 5x from 25 to get your X
x=25/5
x=5
Hope this helps!!

Answer:
10.6 cm to the nearest tenth.
Step-by-step explanation:
If we let one side = x. So as each side of a square are equal, and using Pythagoras we have:
x^2 + x^2 = 15^2
2x^2 = 225
x^2 = 112.5
x = √112.5
x = 10.61.
-12°C is colder than -5°C.
