if a storage tank is holding 450 litres when it is three - quarters full, how much will it contain when it is two-thirds full?

Step-by-step explanation:

Let the total capacity of the tank be x.

When it's

3

4

full it can contain 450 liters.

Now lets find its total capacity. If

3x

4

=450 then x=

4.450

3

=600

So when it's

2

3

full, there will be

2.600

3

=400 liters.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
