LET THE NUMBER BE X
60%OF X=12
60/100 * X=12
3X/50=12
3X =12*50
3X=600
X=600/3=200
THE NUMBER IS 200

Let Henry's age be x
Mary's age = 9 + 3x

I believe you have to get all the like terms on the same side. So since 7m+n is being divided by Q in order to move it to the other side of the equal sign you must multiply each side by Q. Then you would end up with 7m+n=2m(q). 7m and 2m are alike so you then take the 2m and subtract it from each side. So your equation should look like 7m-2m+n=Q. Then combine your like terms and you end up with 5m+n=q
A line is never ending on both ends, while a ray has a point where it stops on one of it's points, but goes on forever on the other one.
