Jackson can remove the shingles off of a house in 7 hours, while martin can remove the shingles in 5 hours. how long will it take them to remove the shingles if they work together?

Step-by-step explanation:

WE can use the following formula:

Where "T" is the time time working together, "A" the time for person A working alon and "B" is the time for person B working alone.

Based on the data given in the exercise, we can identify that:

Therefore, substituting these values into the formula and solving for "T", we get that this is:

Since 1 hour has 60 minutes:

Therefore, if they work together, it will take them 2 hours and 55 minutes to remove the shingles.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
