I have been at this for an hour please help
Jason can paint a room in 6 hours. Lorissa can paint a room in only 3 hours.
Which of the following can be used to determine the amount of time it would take for Jason and Lorissa to paint a room together?
1 over 6 plus 1 over 3 equals 1 over x
1 over 6 plus 1 over x equals 1 over 3
1 over x plus 1 over 3 equals 1 over 6
1 over 3 plus 1 over 6 equals x over 9
For this case we have: Jason can paint a room in 6 hours: 1/6 Lorissa can paint a room in only 3 hours: 1/3 the amount of time it would take for Jason and Lorissa to paint a room together is: 1/6 + 1/3 = 1 / x Answer: 1 over 6 plus 1 over 3 equals 1 over x
