PLEASE HALP ITS IMPOSSIBLE
Current work:
.18x+0(10-x)=1.2
.18x+0(10-x)=1.2
To make 10 L in total you will need x L of the 18% solution and 10-x L of water.
.18x + 0(10-x) = .12(10)
.18x = 1.2
x = 1.2/.18 = 120/18 = 20/3
He needs 20/3 L or 6 2/3 L of water.
(btw, a Russian would never dilute his alcohol)
.18x + 0(10-x) = .12(10)
.18x = 1.2
x = 1.2/.18 = 120/18 = 20/3
He needs 20/3 L or 6 2/3 L of water.
