A solution containing 10% benzene is to be mixed with a solution of 26% benzene to make 500L of a
solution that is 20% benzene. How much of each
solution is to be used?

u rich

step-by-step explanation:

1. perpendicular

2. parallel

3. perpendicular

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
