You have seven quarters and four pennies.
q + p = 11
p + 3 = q
(p + 3) + p = 11
2p + 3 = 11
2p = 8
p = 4
11 - 4 = 7

A piggy bank has quarters and nickels in it There are eight more nickels than quarters if the total value of the coins is 6.10 how many of each coin are there?
Let X equal the number of quarters X * 25 is the value of the quarters ((X+8) * 5) is the value of the nickels25X + 5X + 40 = 610 so 30X + 40 = 610 .subtract 40 from both sides , divide both sides by 30X = 19There are 19 quarters and 27 nickels in the piggy bank
How do you do the math for a brick that balances with three quarters of a brick and three quarters of a pound?
1 brink = (¾+¼) brick = ¾ brick + ¼ brick If 1 brick balances ¾ brick + ¾ lb then: 1 brick = ¾ brick + ¼ brick = ¾ brick + ¾ lb → ¼ brick = ¾ lb (subtracting ¾ brick from both sides) → 1 brick = 3 lb (multiplying both sides by 4).
John has a total of 13 coins in his pocket of the 13 coins thay are all either quarter or dimes the total value of the coins is 2.50 how many quarters does john have his pocket?
The first step in solving this problem is to build two equations. 0.25Q+0.10D=2.50 and Q+D=13 where Q=total number of quarters and D=total number of Dimes. Next we try to subtract one equation from the other to eliminate one variable. So we multiply 0.25Q+0.10D=2.50 by 4 to get 1Q+0.4D=10. Then we subtract Q+0.4D=10 from Q+D=13. This results in 0.6D=3. We divide both sides by 0.6 and end up with d=5. Therefore we have 5 dimes, which equals 50 cents. Therefore we have $2 in quarters or 8 quarters. 8 quarters is the answer.
