Ou have the following 3 equations: 6x + 3y + z = 22
x + 4y – 2z = 12
4x – y - 5z = 10
Write these equations on the form Ax = d.

1. 22

2. 1

3. 7

4. 18

step-by-step explanation

e2020 got it right

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

he earned 78.75 in interest.
