X=8
Set up proportions would give you: 10/3x+1 = 22/7x-1
With that in mind, cross multiply, which would give you: 10(7x-1) = 22(3x+1).
Turns into: 70x -10 = 66x+22. Then just solve for x
Answer:125
Step-by-step explanation:
Answer:
100
Step-by-step explanation:
Let x be the amount to be added of the second solution. For every 100ml of it 8 units of minoxidil are added. The total amount of solution will be (100 + x), so the final concentration is given by:
[Multiplying by (100 + x)]
[Transposing terms]
[
operating]
[Dividing by 0.02]
