We know that Pam spends 45 minutes going to work and 60 minutes when go to home from work. And we are told to write the ratio of minutes spent on driving from home to work to minutes spent on driving to home from work.
Going to work => 45 Going back to home => 60
Easy. 45:60 or 45/60. Now like a fraction, we must simplify. Find two numbers that will evenly divide into both top and bottom.
15 should do.
45/60 / 15/15 = 3/4
So, the ratio is 3:4 or if you want in a fraction form, 3/4.
Y coordinate on solving both equations comes out to be 0 -2x+3y=-6 3y = -6+2x put the value of 3y in equation 2nd 5x-2(-6+2x) =15 5x+12-4x = 15 x=3 put value of X in 3y = -6+2x 3y = -6+2*3 = -6+6 = 0 thus y = 0
