Write the following as algebraic expressions: after a teacher handed out m packs of notebooks with c notebooks in each pack, he has 13 notebooks left. how many notebooks did he have originally?

mc + 13

Step-by-step explanation:

Each pack contained c notebooks.

So, m packs contained mc notebooks.

The teacher handed out mc notebooks and had 13 notebooks left over.

He must have originally had mc + 13 notebooks.

do you have the measurements?

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
