let number of nickels be x
so number of dimes will be 2x -12
the entire stack is worth 2.55
so 5x + 10(2x - 12) = 2.55
solve for x

k so nickel is 5 cents and dime is 10 cents so u multiply numbre of nickels times 5 to get the amount of money and you do the same with dimes
so u get
5x + 10(2x - 12) = 255

I still dont understand
OpenStudy (anonymous):
what part u dont get ?
OpenStudy (anonymous):
All of it:(
OpenStudy (anonymous):
k so the problem says "A stack of nickles and dimes is worth $2.55"
which means you have a nickels and dimes wholse value adds up to $2.55 which is also 255 cents
nickel has values of 5 and dime has value of 10
