Kelly has 4 dimes and some nickels. the total value of her coins is $2.25. write an equation for this.

Step-by-step explanation:

We know that

1 dime = 10 cents

1 nickel = 5 cents

1 dollar = 100 cents

It is given that Kelly has 4 dimes and some nickels.  

Let x be the number of nickels.

        ... (1)

The total value of her coins is $2.25.  

Total value = $2.25 = 225 cents         ...(2)

From (1) and (2) we get

The number of nickels is 37.

Hence, the required equation is 40+5x=225.

answer: the answer is 127 degrees

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
