Jim and Joe both score 36 points in a game. Jim scores 2 times as many as Joe. How many points does each score. How do I solve t

Art [367]

Divide 36 by 3 to get 1/3 of the total, and it says Jim scores 2 times as much so joe scored 12 and Jim scored 24 because 12x2=24. So in conclusion Jim scored 24 and joe scored 12. Hope this helped.
