<u>Answer:</u>
Nickels = 44.6
Dimes = 3.4
<u>Step-by-step explanation:</u>
We know that Jessica has 48 coins of which some are nickels and some are dimes so we can write it as:
n = amount of nickels
d = amount of dimes
--- (1)
We are to find the number of nickels and dimes if their total worth is $3.25.

Answer:
Kim is 16 years old and her sister is 8 years old.
Step-by-step explanation:
We can use equations to represent this scenario.
Let Kim's age be 'k' and her sister's age be 's'.
Thus, k=2s (since Kim's age is double of her sister)
and k+s=24 (their ages add to 24 (from question)
Substituting the first equation:
2s+s=24
3s=24
s=8
Therefore, Kim's sister is 8 years old.
Now substitute this value into the second equation:
k+8=24
k=16
Therefore, Kim is 16 years old.
