Irina:
---------------------------------------------------------------------------
Irina takes 7 hours to paint the room.
In 1 hour, Irina can paint 1/7 of the room.
---------------------------------------------------------------------------
Paulo:
---------------------------------------------------------------------------
Paulo takes 6 hours to paint the room.
In 1 hour, Paulo can paint 1/6 of the room.
---------------------------------------------------------------------------
Both paint together:
---------------------------------------------------------------------------
In one hour they can paint (1/7 + 1/6) of the room.
1/7 + 1/6 = 13/42
So, it takes 13/42 of the room takes 1 hour.
---------------------------------------------------------------------------
Find the number of hours
---------------------------------------------------------------------------
13/42 of the room = 1 hour
Whole room = 1 ÷ 13/42
Whole room = 1 x 42/13
Whole room = 3.23 hours
---------------------------------------------------------------------------
Answer: They need 3.23 hours to paint the room.

Answer: 80 minutes
Step-by-step explanation:
Hi, to answer this question we have to write an equation for each tank:
An empty 1200 gallon tank is filled with water at a rate of 6 gallons of water per minute.
So, the amount of water of the tank is equal to the filling rate, 6 liters per minute (6m)
- Tank 1 =0 (empty )+ 6m =6m
The second 1200 gallon tank full of water is being drained at a rate of 9 gallons per minute.
So, the amount of water in the tank is equal to the amount of water already in the tank (1200 g), minus the draining rate (9m)
Since both tanks will have the same amount of water:
6m = 1200-9m
Solving for m (minutes):
6m+9m= 1200
15m = 1200
m= 1200/15
m= 80 minutes
Feel free to ask for more if needed or if you did not understand something.
Is/of =%/100 so x/59.99=14%/100 Cross multiply to get the answe
