Answer:
Whats F five is that a point or something???
Step-by-step explanation:
2.4 hours
You can get this by setting up the equation:
x/4 + x/6 = 1
Where x is equal to the amount of hours spent working. In this equation x/4 would be Doug. In 4 hours he would paint on room. x/6 would be Elaine. When you add them together using common denominators, you can find x.
Es x2 o 2x ? Porque con x2 no se podrá resolver, tendría que ser 2x
