Leon has a handful of of dimes and quarters valuing $3.40. He has 6 more dimes than he does quarters. How many of each coins doe
lesya [120]

Answer: 14 dimes and 8 quarters

<u>Step-by-step explanation:</u>

dimes ($0.10): x + 6

quarters ($0.25): x

Cost*quantity of dimes + Cost*quantity of quarters = Total value

0.10(x + 6) + x(0.25) = 3.40

0.10x + 0.60 + 0.25x = 3.40

0.35x + 0.60 = 3.40

<u>            -0.60  </u> <u>-0.60 </u>

0.35x             = 2.80

<u>÷0.35            </u>  <u>÷0.35 </u>

      x              = 8

dimes: x + 6   = 8 + 6   = 14

What is 5 1/6 divided by (2 2/3 multiplied by 1 3/8)
Karo-lina-s [1.5K]
So first you need your denominators to be the same so you can multiply. They share a common denominator of 24. 2/3 equals 16/24 and 2/8 equals 9/24. So now you need to turn your fractions into mixed numbers and multiply. Which equals 2112/576. That # is way to big so then you simplify and get 11/3. so now you have 5 and 1/6 divided by 11/3. So now just flip the second fraction multiply it by its reciprocal. 31/6 X 3/11=___. So your final answer is 1 and 9/22
