Answer:
9/44 of an hour, or just over 12 minutes
Step-by-step explanation:
Person 1 + Person 2 divided by Person 1 x Person 2 = Both together
9 + x / 9*x = 5
9+x/9x = 5
Multiply both sides by 9x
9 + x = 45x
Subtract x from both sides
9 = 44x
Divide by 44 to get x.
9/44 of an hour
The greatest common factor is 2. So you have to factor out 2 from the equation. So it is (5+m)2.
So it would be 1.2=X-0.4 and solve to get your answer. Output means the y-intercepts.
