Question

Jim has 50 coins. nickels and dimes more $4.15. How many nickels and dimes makes this amount.?

Answer 1

We are not in school let us have a break!!

Answer 2

33 dimes, 17 nickels.

Answer 3

x = nickles

y = dimes

total of 50 coins, so x + y = 50.

total of $4.15, so 0.05x + 0.10y = 4.15

The rest is for the student to figure out.

Answer 4

x + y = 50

y = 50 - x

x = nickels

y = dimes

.05x + .10y = 4.15

.05x + .10(50 - x) = 4.15

.05x + 5 - .1x = 4.15

.85 = .1x - .05x

x = 17

50 - 17 = 33

y = 33

Answer 5

n+d=50

.10d+.05n=4.15

d=50-n

.10(50-n)+.05n=4.15

5-.10n+.05n=4.15

-.05n+5-5=4.15-5

-05n=-.85

-.05n/-05=-.85/-05

n=17

d=33

3.30 in dimes AND .85 in nickels=$4.15

Answer 6

50.

You just said he had fifty coins of nickels and dimes which came to $4.15, so obviously he has fifty nickels and dimes that make that amount.

x + y = 50

5x + 10y = 415

x = 50 - y

5(50 - y) + 10y = 415

250 - 5y + 10y = 415

250 + 5y = 415

5y = 415 - 250

5y = 165

y = 33

x = 17

x = nickels, which is why you have the 5x at the beginning, to represent 5 cents. y = dimes, which is why you have the 10y at the beginning, to represent 10 cents.

Answer 7

x+y=50

0.1x+0.05y=4.15

solve it
