Rob has $1.65 in nickels and dimes. he has 25 coins in all. how many of each kind of coin are there?explain how you got your answer and show your work.

The number of nickels is 17 and number of dimes is 8.

Step-by-step explanation:

Let the number of nickels be x and number of dimes be y.

Total number of coins is 25.

                  .... (1)

                    .... (2)

On solving (1) and (2), we get

Put this value in equation 1.

Therefore the number of nickels is 17 and number of dimes is 8.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

slope= 1

y-inter slope= 0
