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 .
Answer:
m∠B=143°
Step-by-step explanation:
we know that
<u><em>Vertical Angles</em></u> are the angles opposite each other when two lines cross. They are always equal
so
In this problem we have that
m∠A=m∠B ----> by vertical angles
substitute the given values and solve for x
Find the measure of angle B
m∠B=(5x-7)°
substitute the value of x
m∠B=(5(30)-7)°
m∠B=143°
