Answer:
Two angles are called supplementary when their measures add up to 180 degrees.
Answer:
y=x−3
Step-by-step explanation:
Flip the equation.
4y+7=4x−5
Add -7 to both sides.
4y+7+−7=4x−5+−7
4y=4x−12
Divide both sides by 4.

y=x−3
ik this doesnt make any sense but hope this helps :/
Answer:
A) 80
Step-by-step explanation:
b/4-23=-3
b/4=-3+23
b/4=20
b=20*4
b=80
Hello!
In order to find out the volume of any prism, you are to do length x width x height.
Because we only know the length and the width, we can multiply those to get started. 3 x 5 is 15, so we know that's what we can start with.
Because we know the volume, all we have to do is do h x 15 = volume (45). Now, what is height?
In order to find the height, we must find a number that, when multiplied by 15, equals 45.
So we can try out 3, which when multiplied by 15, equals 45.
That means 3 is your height.
Hope I helped! :)
B imakes the most sense so I agree it is b
