  • this is how you do the math: painter joe= 2 hours painter bob= 3 hours together... 1/2x (that is joe) + 1/3x (that is bob)=1 multiply both sides by 6 and you get 3x + 2x=6 5x=6 x= 5/6 thank god for precalc class.
  • 2 hrs. Bob is a slacker. He's fired. Joe paints room by himself. Time is money. Bob is wasting both. I just LOVE being given a downrate by people with no sense of humor!!!
  • its 5x=6 therefore x= 6/5
