Answer:
y-5=3 can be the correct answer
Given that 1 pint is equal to 437 ml
and 1000 ml=1 liter
then
1 pint =(437/1000) liters
simplifying we get:
1 pint= 0.437 liters
thus amount of pints in 4 liters will be:
4/0.473
=8.45666586
~8.5 pints
The third one because as x increases, y decreases and all the points are around a single line
We have the sum of cubes identity
and observing that 1 + 4 = 2 + 3, we have
and
Then
Alternatively, we have the well-known sum of cubes formula
The sum under the square root is this sum with 
. Then
and so the square root again reduces to 15.
6+6=12
8+4=12
or if you mean algebraic equation:
6+x=12
x+4=12
