Answer:
12
Step-by-step explanation:
12 dimes is $1.20, so your total for the quarters is $3.25. Since there are 25 coins total and 12 of them are dimes, 25 - 12 = 13, so you have 13 quarters. 13 times its value of 25 cents leaves you with $3.25, fulfilling your needed total.

Answer: y = -8.5
<u>Explanation:</u>
  5.1y + 21.3 = -0.3y - 24.6
<u>+0.3y          </u>   <u>+0.3y           </u>

<u>           -21.3 </u>    <u>         -21.3 </u>
 5.4y           =           -45.9
<u>÷5.4          </u>     <u>          ÷5.4  </u>
       y           =          -8.5
