Harriet earns the same amount of money each day. Her gross pay at the end of 7 work days is 35h + 56 dollars. Which expression r

Aleks [24]

Answer:

The expression that represents her gross pay each day will be: $(5h+8)$ dollars.

Step-by-step explanation:

Suppose, Harriet's gross pay each day $= x$

So, her total gross pay for 7 work days $=7*x= 7x$

Given that, her gross pay at the end of 7 work days is $(35h + 56)$ dollars.

So, the equation will be.......

$7x= 35h+56 \\ \\ x=\frac{35h+56}{7}\\ \\ x=\frac{35h}{7}+\frac{56}{7}\\ \\ x=5h+8$

Thus, the expression that represents her gross pay each day will be: $(5h+8)$ dollars.

There are multiple ways in which Anita can divide the sheet of paper for her calendar. First she can have it halved first then, divided by 6 or she can have it divided by 4 and divided each quarter by 3. Either way, each month would take up 1/12 of the total area of the paper.
