Can anyone help please I don’t understand how to do it 2) A builder is tiling a new bathroom and requires 30 tiles which are of
length z and height y. Find an equation that would show the area of the tiled
parts of the bathroom in terms of x and y.

A= 30zy

Step-by-step explanation:

Let the area of the tiled parts of the bathroom be A.

A= area of 30 tiles

A= 30( length × height of tiles)

A= 30(z)(y)

A= 30zy

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
