You may be thinking of the brain-teaser that reads "You have 2 coins that add up to 30 cents but one of them is not a nickel. What are the coins?" The answer of course is a quarter and a nickel; the quarter is the one that's not a nickel!
3 quarters & 2 nickels
he has 27 dimes. to add on, he has 8 nickels to make your total of 3.10
a Dime. 10 cents
I am assuming this means what different combinations of coins would add up to 17 cents. You could have one dime, one nickel and 2 pennies, 1 dime, 7 pennies 3 nickels, 2 pennies 2 nickels, 7 pennies 1 nickel, 12 pennies 17 pennies
This is an algebra problem that requires two equations to be solved simultaneously. The two key pieces of information are that there are 16 coins and that they add to 1 dollar. For the first equation, let's suppose we have X nickels and Y dimes. Therefore we may say: X + Y = 16 For the second equation we apply what we know about the values of nickels and dimes. A nickel is worth 5 cents. So the value of X number of nickels is 5*(X). The value of Y dimes is 10*(Y). Notice that the units of this value is in cents. Our given information says dollar, so it now makes sense to think of this dollar as 100 cents to match our equation. Now we may say: 5X + 10Y = 100 These two equations can be solved simultaneously by add/subtracting them or solving for a variable and substituting. I think add/subtracting is cooler but everyone knows substitution: Rearrange X+Y=16 to X=16-Y Then substitute for X in the other equation: 5(16-Y)+10Y=100 Distribute, group terms, subtract, and divide both sides: (80-5Y)+10Y=100 80+5Y=100 5Y=20 Y=4 Therefore we have 4 dimes, or 40 cents. The total is a dollar so we must have 60 cents in nickels. The only way to have that is with 12 coins. These numbers make sense: they total 16 coins and 1 dollar. QED.
3 quarters & 2 nickels
60
One quarter, three dimes, and five pennies add up to sixty cents. And also 3 dimes and 6 nickels.
two quarters, two dimes and a nickel: One half dollar, and one dime and two nickels
four dimes equal 40 cents ten nickels equal fifty cents ten pennies equal 10 cents Add the 3 groups of coins for one dollar
1. A quarter 2. A nickel Only one of them *isn't* a nickel! XD
you phrased the question wrong "what two coins add up to 30 cents, one can't be a nickel" the answer would be a nickel and a quarter because one isn't a nickel, it's a quarter while the other is a nickel
A nickel is worth 5 cents so 55 nickels are worth 5 * 55 = 255 cents, or $2.55
14 Quarters = $3.50 28 nickels = $1.40 To get this answer you simple add 2 nickles to one quarter which = 35 cents divide 4.90 by 35 which equals 14 14 will be the number of quarters and double that, 28 will be the number of nickels
A nickel is worth 5 cents, so 3 nickels are worth 3*5 = 15 cents. Add the 3 remaining cents to get a total of 18 cents.
Two dimes, a nickel, and 10 pennies. A good question is how do you figure that out. I started out eliminating the coins that could not be included. If one coin was a quarter, the other 12 had to add up to 10 cents. That can't happen so there can't be any quarters in the answer. Then I knew that the number of pennies had to be 0, 5, or 10 since there is no way for the remaining dimes and nickels to to add up to 35 cents if there were another number of pennies. If you had 5 pennies, then 8 coins would have to add up to 30 cents. Even using all nickels would only use up 6 coins so there had to be more pennies. I then went to 10 pennies and that left 3 coins to get to 25 cents. That's where I came up with 2 dimes, 1 nickel, and 10 pennies.
he has 27 dimes. to add on, he has 8 nickels to make your total of 3.10
