Answer:
5(0.05) + 0.10x
Explanation:
This would be correct because, first of all, you have 5 nickels. The value of a nickel is 0.05, and you would then multiply that by 5. That's how we would get 5(0.05)
Next, we know the value of a dime is 0.10 (10 cents), but we don't know how many dimes there are. So, the unknown amount of dimes would be represented by x. Then, we multiply 0.10 by x.
We also want to add the two expressions, because of the word "and."
So, altogether, we would get 5(0.05) + 0.10x
