Question 179738: A 60% antifreeze solution is to be mixed with a 10% antifreeze solution.In what ratio (x/y)must they be mixed to obtaiin a 40% antifreeze solution?(hint:Let N be the number of litres of the 40% solution) Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Let = liters of 40% solution
Let = liters of 60% solution
Let = liters of 10% solution
How much antifreeze is in the 40% solution?
(1)
(2)
Multiply (2) by and subtract from (1)
(1)
(2) answer
check:
Suppose liters
(1)
(2)
Multiply both sides of (1) by and
subtract (2) from (1)
(1)
(2)
(2)
OK
