Shanice wants to make a 72% alcojol solution. She has already poured 2L of pure water into a beaker. How many L of a 90% alcohol solution must she add to this to create the desired mixture

Using the given information, solve for x. what is the length of ab? what is the length of rs? a) x = 2; ab = 4; rs = 8 b) x = 6; ab = 8; rs = 16 c) x = 4; ab = 6; rs = 12 d) x = 8; ab = 10; rs = 20
