order to fill the tank completely ?
(1) 28 litres (2) 18 litres
(3) 12 litres (4) 22 litres​

Answer 1

Answer:

4/5 x) - 8 liters = 2/3 x

Solving for x, x=60 liters

X is the total number of liters the container holds.. This is not what the question asked, but it makes it possible to calculate the answer.

Now we can find the number of liters we started with. 4/5 of 60 is 48 liters. Then we took 8 liters away. Now we have 40 liters.

40 liters + y = 60 liters. In this equation we solve for y. y = 20. We would need to add 20 liters to fill up the container.
