it asked to combine like terms, you still have to do that.
= 6d + 7n
Is #2 a continuation of #1 ? I will assume it is
so d = 9 and n = 18
so sum = 6(9) + 7(18) = 180
Please check to see if I did this correctly. This is a 2 part math problem.
1. Janelle has d dimes and n nickles. Her sister has 5 times as many dimes and 6 times as many nickles as Janelle has. Write the sum of the number of coins they have, and then combine like terms.
This is the answer I came to: d+n+5d+6n
2. If Janelle has 9 dimes and 18 nickles, how many total coins do Janelle and her sister have?
This is the answer I came to:
9d x 5d + 18n x 6n = 45 + 108 = 153 coins
