Can some one me with this i need it broken down on how i got the answer

Step-by-step explanation:

Let the dimes = d

Let the nickels = q

d + q = 24

(0.1)d + q(0.25) = 3.75   multiply this equation by 100 to get rid of the decimals.

10d + 25q = 375    

Write the bottom equation first and the top equation * 10 second

10d + 25q = 375

10d +  10q = 240         Subtract. The n s cancel.

         15q =  135          Divide by 15

q = 135/15

q = 9

d + q = 24

d + 9 = 24                   Subtract 9 from both sides.

d = 24 - 9

d = 15

Check

There are 15 dimes and 9 quarters.

15 * 0.1 = 1.50

9 * 0.25= 2.25

Sum = 3.75 which is what you were given.

what is all that apply?
