The carpenter makes 1/4 of the job per hour.
The assistant makes 1/6 of the job per hour.
When they work together, they make 1/4 + 1/6 = 6/24 + 4/24 = 10/24 = 5/12 of the job each hour.
Thus, it will take 12/5 = 2 2/5 hours = 2 hours and 24 minuets for them to finish the job working together.
Answer:
3
Step-by-step explanation:
The most basic approach here is to simplify as much as possible. Therefore you do:
(1/2 x 8x + 1/2 x 4) - (1/3 x 3x + 1/3 x 9) =17
(4x + 2) - (x + 3) = 17
4x + 2 - x - 3 = 17
3x - 1 = 17
Then you pass the one on the other side which gives:
3x = 17 + 1
3x = 18
Finally divide everything by 3:
x = 6
