1. C=2πr
We need to move r by itself on a side of the equation.
Divide both sides of the equation by 2π. This will cancel out the side with the r.
r=C/2π
2. A=1/2*b*h
Divide both sides by 1/2*h, isolating b
b=A/
h
3.y=mx+b
Now we have to do reverse PEMDAS, we have to add/subtract before we can multiply or divide to simplify.
Subtract both sides by b
y-b=mx
Now divide both sides by m
x=![\frac{y-b}{m}](https://tex.z-dn.net/?f=%5Cfrac%7By-b%7D%7Bm%7D)
Remember we have to divide both terms y and -b by 2, so it goes on the bottom for both.

Answer:
The LCM of 9 and 12 is 36. The GCF is 3
Step-by-step explanation:
To get the Least Common Multiple (LCM) of 9 and 12 we need to factor each value first and then we choose all the factors which appear in any column and multiply them: 2 x 2 x 3 x 3 = 36
To get the Greatest Common Factor (GCF) of 9 and 12 we need to factor each value, that should give you 3.
