Answer:
<em>6 days</em>
<em></em>
Step-by-step explanation:
Let the time taken by Carpenter working alone =
days
Then time taken by apprentice alone = Twice as that of taken by Carpenter = 2
days
Time taken working together = 2 days
Work done in one day working together = 
Work done in one day by Carpenter working alone = 
Work done in one day by apprentice working alone = 
Work done in one day by Carpenter working alone + Work done in one day by Carpenter working alone =
+
= Work done in one day working together = 

Time taken by Carpenter alone to complete the work = 3 days
Time taken by Apprentice alone to complete the work = 3
2= <em>6 days</em>

6x=7+8
2 Simplify 7+87+8 to 1515.
6x=156x=15
3 Divide both sides by 66.
x=\frac{15}{6}x=

Answer:
I believe it would be 9 hours for company 1, and 10 for company 2
Step-by-step explanation:
30 x 9 = 270 (+ the first 20) =290
25 x 10 = 250 (+ the first 40) =290
So you know the whole line is XZ which is 83.Then you find out it is in two parts so that is XY and YZ which are 11 and 4c. You can make the equation:
11+4c=83
4c=72
c=18
c=18 and YZ=72
