Answer 2

Answer:

boys =17.64 ,girls=35.28

Step-by-step explanation:

let x

let x3x +6x =53

let x3x +6x =53 9x=53

let x3x +6x =53 9x=53 x=53/9

let x3x +6x =53 9x=53 x=53/9 x= 5.88

let x3x +6x =53 9x=53 x=53/9 x= 5.88 3x=3×5.88=17.64

let x3x +6x =53 9x=53 x=53/9 x= 5.88 3x=3×5.88=17.64 6x=6×5.88=35.28

let x3x +6x =53 9x=53 x=53/9 x= 5.88 3x=3×5.88=17.64 6x=6×5.88=35.28So,boys= 17.64

let x3x +6x =53 9x=53 x=53/9 x= 5.88 3x=3×5.88=17.64 6x=6×5.88=35.28So,boys= 17.64 girls=35.28
