    There are 60 marbles in the bag

    Step-by-step explanation:

    The total number of marbles times the probability of red marbles = number of red marbles

    total * 7/10 = 42

    Multiply each side by 10/7

    total * 7/10 * 10/7 = 42*10/7

    total

    60

    There are 60 marbles in the bag
