I forgot how to show the work to these kinds of questions -3 < 2x + 7

The answer is -5<x

Step-by-step explanation:

-3<2x+7

Subtract 7 from both sides

-10<2x

Isolate x by divided both sides by 2

-5<x

$54.99

step-by-step explanation:

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99

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
