AZ:

40 = 1/2 (7x - 3x) what is 7x - 3x = ?

AZ:

ohh we were supposed to solve for CD after we find x, we're supposed to find CD

AZ:

we had found x = 20 the circle is CD + 7x + 3x = 360

imyoursgirlsgirl:

so rn its CD+4x=360

AZ:

no, what is 7x + 3x = ??

imyoursgirlsgirl:

10x sorry i thought u said -

AZ:

so CD + 10x = 360 and x = 20 so 10x = 10 * 20 = ??

imyoursgirlsgirl:

so 10x=200

AZ:

yes and now we have CD + 200 = 360 so CD = 360 - 200 = ??

imyoursgirlsgirl:

160

AZ:

There you go!
