You have a total of $3.25 in change made up of 25 pennies, 6 nickels, 2 dimes, and x quarters. How many quarters do you have?
coldgirl [10]

Answer:

10 quarters

x=10

Step-by-step explanation:

25 pennies equals to .25 ⊄

6 nickels equals to .30⊄

2 dimes equals to .20⊄

Add it up: 25+30+20=75⊄

You will then subtract .75 from our total:

3.25-.75=2.50

You need 2.50 in quarters; remember .50 for two quarters and 1.00 for four.

Eight quarters will equal 2.00

and two quarters equals 50.

Add it up, 10 for 2.50.

You will have 10 quarters.

X=10

Erica bought 3 1/2 yards of fabric if she uses 2/3 of the fabric how much will she have left?
RoseWind [281]
First, convert 3 1/2 into an improper fraction, which is 7/2. Now, you have to make sure both sides have a common denominator. This will be 6. So now the equation is 21/6 - 4/6. Subtract the numerators, which is 17. Keep the denominator, however. Now, simplify. You new answer will be 2 5/6.
