Step-by-step explanation:

Step-by-step explanation:

1/3 x = 12

or, x = 12 * 3

or, x = 36

3x + 3 =21

or, 3x = 21 -3

or, 3x = 18

or, x = 18 ÷ 3 = 6

3/2 x -4 =16

or, 3/2 x = 16 + 4

or, 3/2 x = 20

or, 3x = 40

or, x = 40/3

the equation given is 9.95 + 0.30s

for 35 songs; s = 35

9.95 + 0.30* 35

= 9.95 + 10.5

= 20.45

last question

let the cost of t shirt be x

11* x - 6 = 27

11x + 6 = 27

24/56=hx^7
