SOLVE FOR X. pls i need help

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

dangina [55]

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:

$4 / (100 + x) + 0.08x / (100 + x) = 0.06$ [Multiplying by (100 + x)]

$4 + 0.08x = 6 + 0.06x$ [Transposing terms]

$0.08x - 0.06x = 6 - 4$ [ operating]

$0.02x = 2$ [Dividing by 0.02]

$x=100$
