Acollection of nickels and quarters is worth $2.85. there are three more nickels and quarters. how many nickels and quarters are there

There are 9 quarters and 12 nickels

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.

i believe a. 12x≥120 is the answer
