Answer:


The equations have the same slope but different y-intercepts. This means the lines are parallel and there is no solution (since they do not intersect).
Circumference is diameter times pi, diameter is radius times 2. The answer should be 57 inches.
First isolate x by multiplying by x on both sides. It will look like this:
(2/3)x=1.2
Then devise by (2/3) on both sides to get:
x= 1.2/(2/3)
The easiest way to get this is plug that into a calculator and get the answer:
x=1.8
