A plumber and his assistant work together to replace the pipes in an old house. The plumber charges $30 an hour for his own labo
Korvikt [17]

Answer:

The plumber worked 50 hours, and his assistant worked 25 hours.

Step-by-step explanation:

Since a plumber and his assistant work together to replace the pipes in an old house, and the plumber charges $ 30 an hour for his own labor and $ 20 an hour for his assistant's labor, and the plumber works twice as long as his assistant on this job, and the labor charge on the final bill is $ 2000, to determine how long did the plumber and his assistant work on this job the following calculation must be performed:

40 x 30 + 20 x 20 = 1200 + 400 = 1600

50 x 30 + 25 x 20 = 1500 + 500 = 2000

Therefore, the plumber worked 50 hours, and his assistant worked 25 hours.

How do I solve x≤100
Molodets [167]

Answer:


Step-by-step explanation:

There's really nothing to solve here.  Rather, you should describe what x≤100 represents.

To draw an appropriate graph, draw an x-axis, mark x=100 with a black dot, and then draw an arrow to the left from this dot.  That's it.  "All x less than or equal to 100."
