The answer is A.
This is saying 5E-9/2E4, so it equals 2.5E-13.
Qty · % = Total
Drink 1: x .25 = .25x
Drink 2: 15 - x .10 = .10(15 - x)
Mixture: 15 .21 = .25x + .10(15 - x)
(15)(.21) = .25x + 1.5 - .10x
3.15 = .15x + 1.5
1.65 = .15x
11 = x
Drink 1 (25%) is 11 liters
Drink 2 (10%) is 15 - 11 = 4 liters
Answer: x=y-3 or y=3+x
Step-by-step explanation:
0.057x 10 is equal to .57. All you have to do is move the decimal to the right one time because there is one zero in 10.
