Answer:
2 hours 11 minutes
Step-by-step explanation:
Each hour Sally can paint 1/3 rooms, Steve can paint 1/8 rooms.
If they work together, each hour they can paint 1/3 + 1/8 = 11/24 rooms.
So They will take 1/(11/24) = 24/11 = 2.18 hours to paint a whole room.
2.18 hours = 2 hours 0.18*60 minutes
0.18 * 60 = 11
Answer: 2 hours 11 minutes

Answer:
m = 8
Step-by-step explanation:
5(m+5)=7m+9 (distribute & evaluate parenthesis)
5(m)+5(5)=7m+9
5m + 25 = 7m + 9 (move all m-terms to one side and constants to the other)
5m - 7m = 9 - 25 (evaluate both sides)
-2m = -16 (divide both sides by -2)
m = (-16) / ( -2) = 8
