Question

Help me Please! I will give medals.

Write an equation that can be used to solve: Emilio has 10 more nickels than dimes, and the total value of his coins is $2.90. How many nickels does he have? Let n represent the number of nickels.

Answer 1

i think the answer would be he has 10 nickels and four dimes

Answer 2

Let n represent the number of nickels.
Let d represent the number of dimes.

n = d+10
5n + 10d = 290 cents

Answer 3

1 nickle is 5 cents and 4 nickles is 20 cents.

Answer 4

sorry i was thinking of a quarter

Answer 5

It's ok :)

Answer 6

do you know how many dimes he has

Answer 7

no

Answer 8

okay

Answer 9

@sangya21 I'm still not quite sure on how to work that out, I'm kind of confused...

Answer 10

40 nickels= $2.00 and then add 6 more nickels which will get $2.30 then 6 dimes which will give you $2.90

Answer 11

does that make scene

Answer 12

n = d+10
5n + 10d = 290 cents

use n = d+10 in second eq. to find d
then use that value of d in first eq to find n.

Answer 13

@DawnStar53 does my answer make scene

Answer 14

Would it be 25?
Because the value of a nickle is 5 and you multiply that by 5?
25+10d=290?

Answer 15

who are you talking to @DawnStar53

Answer 16

5(d+10) + 10d = 290
5d + 50 + 10d = 290
15d = 290 - 50
15 d = 240
d = 240/15 = 16

total number of dimes = 16

as number of nickels is 10 more than number of dimes
then, total number of nickel = 16+ 10 = 26

Answer 17

It makes a little bit of sense but it still confuses me.
