If there are 150 nickels and dimes and 70 more are nickels than dimes how many of each are there?
Oh, dude, let's break it down. So, if we let x be the number of dimes, then the number of nickels would be x + 70. Since there are 150 coins total, we can set up the equation x + (x + 70) = 150. Solving it, we find that there are 60 dimes and 130 nickels. Easy peasy, lemon squeezy!
The coins in a cash register total 12.50 and there are only nickels dimes and quarters. There are twice as many dimes as nickels and there are twice as many quarters as dimes. How many many dimes are?
You need to define variables for the different types of coins, write the corresponding equations, then solve them. One equation for each fact. Here are the equations:5N + 10D + 25Q = 1250 D = 2N Q = 2D

Keoki has 22 coins that are all dimes and quarters. If their value is 4.35 how many dimes and quarters does Keoki have?
If Keoki has 14 quarters and 8 dimes (for a total of 22 coins), she has $3.50 and $0.80 or $4.30 in coins. If Keoki has 15 quarters and 7 dimes (for a total of 22 coins), she has $3.75 and $0.70 or $4.45 in coins. If Keoki has 22 coins that are all dimes and quarters and their value in total is $4.35 as asked, there isn't a combination of coins that will permit her to have both 22 coins and $4.35 worth of coins.
Jack knows that he has 40 coins in his pocket all either nickels or dimes If the total amount of money he has equals 3.50 how many nickels does he have?
Let x be the number of nickles. So, the number of dimes is 40 - x. So, 0.05x + 0.10(40 - x) = 3.50 0.05x + 4 - 0.10x = 3.50 - 0.05x + 4 = 3.50 subtract 4 to both sides; -0.05x = - 0.50 divide by - 0.05 to both sides; x = 10 Thus, Jack has 10 nickles and 30 dimes.
