Can someone help me pleas

12x - 84y + 24z

Step-by-step explanation:

When doing these if there is a number outside of the parenthesis then that mean you have to combine those terms by that i mean

12(x -7y + 2z)

12× X is combined to be 12x

12 × -7y = -84y

12 × 2z = 24z

so your new expression would be

12x - 84y + 24z

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
