How can you get 3 1/2x alone on the left side of the equation 3 1/2 x + 215 = 495? what is the resulting equation?

subtract 215 from both sides

x = 80

Step-by-step explanation:

to get the 3 1/2 x alone subtract 215 from both sides.

this moves it to the other side.

495-215 =280

3 1/2 x = 280

divide both sides by 3 1/2

this will solve for x

x = 80

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
