Answer:
1st Circle
Radius = 9
Diameter = 18
Circumference = 2 ×
× r = 2 × 3.14 × 9 = 56.52
2nd Circle
Radius = 14
Diameter = 28
Circumference = 2 ×
× r = 2 × 3.14 × 14 = 87.92

Answer 28 because you plug it in for your answer.
X=1
To solve this you start by adding like terms on the left side and doing the distributive property and adding like terms on the right. This would get you
4x+7=3x+8
Then you minus 3x on both sides getting
x+7=8
Then subtract 7 from both sides getting x=1.
The direct variation equation is y = kx.
In this case, the equation is y = 1.8x.
Substitute the given points into the equation. If the x and y coordinate of a point satisfies the equation and both sides are equal, then that point is your answer.
