Answer 2

@Somy

Answer 3

I would start out by setting up some equations

Let D = Dimes, N = Nickels, and P = Pennies.

If all the coins equal 1.10, what would that equation look like?

Answer 4

This is my 5th grade little brother's math homework and I just completely think this is Algebra! But shouldn't the setup look a little something like this...
D x N x P= $1.10

Answer 5

@FortyTheRapper ^

Answer 17

d+n+p=1,10 $
3n=p
d=p-2

ok. so first you need to solve this sytem for d and p and n - do you can solve it ?

Answer 18

system - sorry

Answer 19

I just need to explain to him how to do it. Full English.

Answer 20

sorry for my english - hope you willé can understanding it right

Answer 23

Yes.

Answer 24

dimes nickels and pennies
d n p

Answer 25

Yes.

Answer 26

so these amount of money is formed from dimes ,nickels and pennies
but you know that from nickels there are 3 time more than pennies
this mean that 3n=p

and the number of dimes is 2 less than the number of pennies so this mean that the number of dimes so d is equal with number of pennies minus 2
yes ?

Answer 27

Yes.

By the way a penny i worth 1 cent.
A dime, 10 cents.
A nickel, 5 cents.

If you didn't know that... Well... I'm sorry for you XD

Answer 38

@fluttershyK, are you my savior?

Answer 39

Do the first one please!!!

Answer 40

P= number of pennies
n= number of nickels
d= number of dines
we have:
(1) 10d+5n+p=110
(2) n=3p
(3) d= p-2
substitute (2) and (3) in (1)
10(p-2)+5(3p)+p=10
or:
10p-20+15p+p=110
26p=130
p=5
from (2); n=15
from (3); d=3

Answer 41
