Can you solve this problem for me?
Nina has twice as many nickels as dimess. In all, she has 70¢. How many nickels and dimes does she have?
dimes --- x
nickels ---2x
value equation:
10x + 5(2x) = 70
20x=70
x = 3.5
NO WAY!! , can't have 3.5 dimes
this question is bogus, no solution.
Check your typing, or the problem is silly.
