Answer:
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
Answer:
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
