The sum of the diameters of two circles is 28 inches. One circle has a diameter that is 8 inches longer than the diameter of the other. What are the diameters of the two circles?
try it from there do you know how to do system of equailets? think of x as one of your diameters and d as the other.
plug in the second equation to the top one lik this:
(d-8)+d=28 then find x and check it by plugging in the number. hope this helps (:
