Answer:

First blank is 15.

Second blank is 60.

Third blank is 8.

$15x-60=8$

Step-by-step explanation:

To clear the fractions, multiply both side by the least common multiple (or a common multiple) of the denominators you see.

The least common multiply of 4 and 5 is 4(5)=20.

So multiply both sides by 20:

$20(\frac{3}{4}x-3)=20(\frac{2}{5})$

$\frac{3(20)}{4}x-3(20)=\frac{2(20)}{5}$

Simplify:

$3(5)x-60=2(4)$

$15x-60=8$

First blank is 15.

Second blank is 60.

Third blank is 8.

A car repair shop charged $80 per hour for labor and $210 for the parts of a car. If the total cost of repair for the car was $4

ohaa [14]

Hello!

$\bf Answer:$

It took $\boxed{ \bf 3.5}$ hours to repair the car.

$\bf Explanation:$

First, subtract the cost of car parts from the total amount spent:

490 - 210 = 280

Divide this by cost of labor per hour:

280 ÷ 80 = 3.5
