Question

kristian had 385 marbles. while making through the kitchen she dropped the marbles, and 11 of them rolled under the refrigerator and were lost. kristian divided the leftover marbles into 11 groups. how many marbles were on each group

Answer 1

34 each group

Explanation:

let "x" be the number of Marble in each group

385 = 11x + 11

-11

374 = 11x

374 / 11 = 34

34 = x

You can check your answer to see if it is correct by solving it with x being "34"

385 = (11 * 34) + 11

11 * 34 = 374

385 = 374 + 11

385 = 385
