Answer:
32 hours.
Step-by-step explanation:
Let x represent the time taken by Russell and Aaron to build the shed.
We have been given that Russell and Aaron can build a shed in 8 hours when working together. Aaron works three times as fast as Russel.
Russell's work rate would be
.
Since Aaron works three times as fast as Russel, so Aaron's work rate would be
.
Part of work done by in one hour would be
.
We can represent our given information in an equation as:

Let us solve for x.




Therefore, it will take Russell 32 hours to build the shed working alone.
Answer:
p = −1
Step-by-step explanation:
1. Regroup terms.
−6 (p + 8) = 7p − 35
2. Expand.
−6p − 48 = 7p − 35
3. Add 6p to both sides.
−48 = 7p − 35 + 6p
4. Simplify 7p − 35 + 6p to 13p −35.
−48 = 13p − 35
5. Add 35 to both sides.
−48 + 35 = 13p
6. Simplify −48 + 35 to −13.
−13 = 13p
7. Divide both sides by 13.
−1 = p
8. Switch sides.
p = −1
