Janelle has d dimes and n nickels. her sister has 5 times as many times and 6 times as many nickels as janelle has. write the sum of the number of coins they have, and then combine like terms

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
