1. kim's age is twice that of her sister. when you add kim's age to her sister's age, you get 36. how old is each sister? (a) write an equation that represents the situation. explain any variable used. (b) solve the equation from part (a). show your work. state your solution as a complete sentence.

im not sure of the names, but the answer is 48

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
