Asidewalk is built 12 bricks wide by laying each brick side by side. how many inches wide is this sidewalk is each brick measures 2 7/8 inches wide?

The sidewalk is 34.5 inches wide.

Step-by-step explanation:

Given:

A sidewalk is built 12 bricks wide by laying each brick side by side.

Brick measures 2 7/8 inches wide.

Now, to find the width of sidewalk.

Width of brick = 2 7/8 = 23/8.

Number of bricks = 12.

So, the sidewalk = width of brick × number of bricks

                            =

                            =

                            =

Therefore, the sidewalk is 34.5 inches wide.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

20%
