If the ratio of boys to girls is 2:3 and there are 15 girls in your class, how many boys are there.

the y will be in still but your answer will be y x 3

step-by-step explanation:

jk: )

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

the scale is 1/9 my friend can't simplify 1 anymore so it will be (for every 1 there's 9)
