What are the three consecutive integers if the sum of the second and thrid exceeds a half of the first by thirty-three?
Let the three consecutive integers be n, n + 1 and n + 2. Then (n + 1) + (n + 2) = n/2 + 33 2n + 3 = n/2 + 33 : 4n + 6 = n + 66 : 3n = 60 : n = 20 The three numbers are 20, 21 and 22.
Tammy has 1 3 as many dimes as nickels 3 more quarters than nickels 17 coins in all?
Nickels = 6 Dimes = 2 Quarters = 9 (1/3N) + N + (3+N) = 17 2 1/3N = 14 N = 6
A collection of 30 coins worth 5.50 consists of nickels dimes and quarters there are twice as many dimes as nickeles how many quarters are there?
Let the number of nickels, dimes and quarters be n, d, q respectively. Then n +d + q = 30 5n + 10d + 25q = 550 But d = 2n, so: n + 2n + q = 30 => 3n + q = 30 5n + 10(2n) + 25q = 550 => 25n + 25q = 550 => n + q = 22 Which gives two simultaneous equations to solve, resulting in: n = 4, q = 18 So there are 18 quarters (plus 4 nickels and 8 dimes).
If you have twice as many nickels as quarters how many quarters are there if you have 4.90?
5n + 25q = 490; n = 2q so: 10q + 25q = 490 ie 35q = 490 so q = 14 and n must be 28. 14 x 25c = $3.50, 28 x 5c = $1.40, total $4.90. ...and there you have it!
How many line segments does a N have?

How many quarters and nickels are in 5.20 if there are only 36 coins?
Q + N = 36;.25Q + .05N = 5.20;.25(36-N) +.05N = 5.20;9- .20N = 5.20;3.8 = .20N;N = 19 and Q = 17

What are the three consecutive integers if the sum of the second and thrid exceeds a half of the first by thirty-three?
Let the three consecutive integers be n, n + 1 and n + 2. Then (n + 1) + (n + 2) = n/2 + 33 2n + 3 = n/2 + 33 : 4n + 6 = n + 66 : 3n = 60 : n = 20 The three numbers are 20, 21 and 22.
What is one third of three quarters of one hundred?
One third of three-quarters of a hundred is twenty five. 3/4 of 100 = 75 1/3 of 75 = 25
How many nickels would you have if you have 32.40 of only quarters and nickels and you have 78 more quarters?
Call the number of nickels n and the number of quarters q. From the problem statement, q = n + 78 and 25q + 5n = 3240. Substituting the first equation into the second yields 25(n + 78) + 5n = 3240, or 30n = 3240 - 1950 or n = 1290/30 = 43 nickels.
How many different ways can you make change for a half dollar without using pennies?

Tammy has 1 3 as many dimes as nickels 3 more quarters than nickels 17 coins in all?
Nickels = 6 Dimes = 2 Quarters = 9 (1/3N) + N + (3+N) = 17 2 1/3N = 14 N = 6
A collection of 30 coins worth 5.50 consists of nickels dimes and quarters there are twice as many dimes as nickeles how many quarters are there?
Let the number of nickels, dimes and quarters be n, d, q respectively. Then n +d + q = 30 5n + 10d + 25q = 550 But d = 2n, so: n + 2n + q = 30 => 3n + q = 30 5n + 10(2n) + 25q = 550 => 25n + 25q = 550 => n + q = 22 Which gives two simultaneous equations to solve, resulting in: n = 4, q = 18 So there are 18 quarters (plus 4 nickels and 8 dimes).
