if i have 2 us coins and they equal 55 cents and one of them is not a nickel what are the coins
One is a 50-cent piece, and the other coin is a nickel.
To solve this puzzle, we need to find two US coins that add up to 55 cents, with one of them not being a nickel.
Let's break it down step by step:
1. Start by assuming one of the coins is a nickel (5 cents). Since one of the coins is not a nickel, let's explore the alternatives.
2. Since the total value of the coins is 55 cents, with one being a nickel, the remaining value of the other coin would be 55 - 5 = 50 cents.
3. Now we have to find a combination of coins that adds up to 50 cents. We know that both coins are not nickels, so we have a few options: dime (10 cents), quarter (25 cents), and half dollar (50 cents).
4. Trying a quarter (25 cents) and a nickel (5 cents) would give us a total of 30 cents, which is less than the desired 50 cents.
5. Trying a half dollar (50 cents) and a nickel (5 cents) would give us a total of 55 cents, which matches the given information.
Therefore, the two coins that equal 55 cents, with one of them not being a nickel, are a half dollar and a nickel.
