Answer 6

is there an answer choice

Answer 15

nope, but I guess there must be 36 :)

Answer 16

I think that the next step is 0.05(245-0.1n)=245 but I'm not sure

Answer 18

I BELIEVE IN YOU @eyust707 and @lilsis76!
GET EM!

Answer 19

@undeadknight26 do you know if the equation above is correct? ^

Answer 20

haha sorry doing this slowly blah . dumb cold! lol

Jose has 2.15 in N & D.
he has 10 more N than D
How many of each does he have? is this the quesion, Right?

Answer 21

:O
I have no involvement yet ;p
Arent you just seeing how many dimes and nickles make up $2.15? O.o

Answer 22

no @undeadknight26 there are 10 more nickels than dimes and yes @lilsis76

Answer 23

Oh makes sense...This takes too much energy and im 2 lazy sowwy </3

Answer 24

okay im trying it out, and i am on this equations
.05x + .10y = 2.15

Answer 25

well i think the equation is right lol gotta see now

Answer 26

Yes then just write one more equation...

Answer 27

ok so (im usind n and d for nickels and dimes) so there is only one unknown variable, that would be 0.05(245-0.1d)=245

Answer 28

is that correct do you know?

Answer 29

okay got it.
are you ready @Lucinda12345 ?

Answer 30

so i gave you the equation: .05x+.10y=2.15
where the x is nickels and y is dimes so we'll change it to n and d

Answer 31

yes :)

Answer 32

.05n + .10d =2.15

Answer 33

now your going to want to mult. by 100 to get rid of the decimals so now we have
5n + 10d = 215

Answer 34

just remember x is the nickels and so we have to do (n-5) for d (or y)
so,
5n + 10 (n-5) = 215
from there you now get
5n+10 (n-5)=215

Answer 35

ok

Answer 36

from there:
you can do the math to get:
5n+10n-50=215

simplify
15n-50=215
simplify more
15n=265
simplify even more
divide both sides by 15
there are 17 nickels. NOW! fill 17 for the beginning equation. and tell me what you get for Dimes.

Answer 37

oh you know that it is $2.45 not $2.15

Answer 38

what? haha well then just do everything the same exact way and tell me what you get.
the way Im explaining it is the way I like things to be explained to me. so lets work it out together and tell me how you are solving it along the way. let me check my answers and the the problem too

Answer 39

ok so if it is 2.45 them umm... hold on

Answer 40

lol okay, ya i know im still doing it. no calc. so using laptop

Answer 41

So that would equal 13 dimes, and 23 nickles! Thank you for the help :)
