Answer:  15  dimes

Step-by-step explanation:

Nickels are 5 cents and dimes are 10 cents  and since they are a total of 1.95 coins in total we can set up the two equations and solve for how much there are for each of the money.

x + y = 24  

0.05x + 0.10y = 1.95   so solve for  y  and  x is the number of nickels while y is the number of dimes.

x+y=24

   -y    -y

x = -1y +24  

0.05(-1y +24) + 0.10y = 1.95

 -0.05y + 1.2 + 0.10y = 1.95

       0.05y + 1.2 = 1.95

                     -1.2   -1.2

          0.05y = 0.75

   y = 15

Strike441 [17]
X(2x²-9x+10)=x(2x-5)(x-2)=0.
x=0 is one solution.
2x-5=0 and x-2=0 give us the solutions x=5/2 and x=2.
So x=0, 2 or 5/2.

You divide 8644 by 8 which equals 1080.5, but since you can't have half of one person you approximate it to 1080 or 1081.
