Victoria weighs 5/7 as much as mario. victoria weighs 125 lb. how much does mario weigh?
ehidna [41]
Let M equals to Mario's weight (M = Mario’s weight) then formulate an equation from the given phrase: "Victoria weighs 5/7 as much as Mario. Victoria weighs 125 lb", so the equation would be: 125 lb = (5/7) M. To solve for M, multiply both sides by 7, then it will result to 875 = 5M then finally, divide both sides by 5 to get Mario’s weight which is equals to 175 lbs.
