10d - 6 = 4d - 15 - 3d10d - 6 = d - 159d = -9d=-1
14d + 20e
Suppose A/B equals a decimal fraction F, which has d digits after the decimal place and then terminates.Then (A/B)*10D = F*10D is an integer.That is A*10D/B is an integer.A and B are coprime so they have no factor in common and therefore B must divide 10D.
3c - 4d = 6d + 4c Subtract 4c from both sides: -c - 4d = 6d Add 4d to both sides: -c = 10d or c = - 10d
Let D = the number of dimes Let N = the number of nickels 10D + 5N = 170 N = D + 10 10D + 5(D + 10) = 170 10D + 5D + 50 = 170 15D = 120 D = 120/15 D = 8 N = 18
