Step-by-step explanation:
90 = (20)(x)
so you have to solve for x
90/.20 =450
answer is 450
If you are mixing a 30% solution with a 20% solution to obtain a 14% solution, you will never obtain a 14% solution.
Answer:
4
Step-by-step explanation:
The mean of 2x and 12 is (2x+12)/2, so we get the equation:
(2x+12)/2 = 10 =>
x+6=10
x = 10-6 = 4
* Your question states four numbers, but you write only two... the answer could be wrong because of that.
