    Step-by-step explanation:

    If Janelle has dimes and nickels, she has d + n. If her sister has 5 times the number of dimes, she has 5d; if her sister has 6 times the number of nickels she has 6n.

    d + n + 5d + 6n - -> 6d + 7n

    Step-by-step explanation:

    d represents the number of dimes that Janelle has.

    n represents the number of nickels that Janelle has.

    Her sister has 5 times as many dimes and 6 times as many nickels as Janelle has. This means that the number of dimes and nickels that her sister has would be

    5d + 6n

    the sum of the number of coins they have would be

    d + n + 5d + 6n = 6d + 7n
