Question 938398: raul has 6 large marbles and 14 small marbles. one large marble weighs the same as 3 small marbles. if the weight of all 20 marbles is 80 ounces, then the weight of 2 large marbles plus 4 small marbles is how many ounces. Answer by ewatrrr(24785) (Show Source):
Hi
Let x represent the weight of a small marble
L =
6(3x) + 14x = 80oz
32x = 80oz
x = 80/32 = 10/4 oz, the weight of a small marble
...
2(30/4) + 4(10/4) = 25oz
