Answer:
6 hours
Step-by-step explanation:
Let the labor hours be x.
The bill comprises of parts cost plus labor cost. Labor cost is hours times the cost per hour. Then we have equation:
- 265 + 48x = 553
- 48x = 553 - 265
- 48x = 288
- x = 288/48
- x= 6
So the answer is 6 hours.
Answer: 5.150
Step-by-step explanation:
1. Multiply 28 by 6/7
2. Multiply 21 by 2/9
3. Divide 24 by 4.66
Is there a picture to find the measure of the acute angle? Or do you want an equation to solve it? If so than it is: 2b-12=a, where b is the measure of the other acute angle and a is the measure of the acute angle where it is twice the difference of the measurment of the other acute angle and 12.
