x=6/7
Step-by-step explanation:
7x÷2+5=8

subtract 5 on both sides
7x÷2=3
multiply 2 on both sides
7x=6
divide by seven on both sides
x=6/7

Answer:
7.25 h = $36.25 is the required expression.
Cat worked 5 hours for the customer as babysitter.
Step-by-step explanation:
The hourly rate paid to cat for babysitting job = $7.25
Let us assume the number of hours cat worked = h hours
⇒The total amount paid for m working hours to Cat
= h x ( Cost of working per hour) = h x $7.25
= 7.25 h
Also, the amount paid to Cat after h hours = $36.25
According to question:
7.25 h = $36.25
or, h = 36.25 / 7.25 = 5
⇒ h = 5
Hence, Cat worked 5 hours for the customer as babysitter .
