500 - 20x = 220

Step-by-step explanation:

$500 is the base cost, and she withdraws $20 per week. $220 would be the final cost, so x represents the amount of weeks.

500-20w=220

Step-by-step explanation:

w=14

it will take 14 weeks to have her balance at 220

-20w=220-500

-20w=-280

divide both sides by -20

w=14

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
