Answer:

r=2q-6

Step-by-step explanation:

10q-5r=30

Subtract 10q from both sides:

-5r=30-10q

Divide both sides by -5:

r=2q-6

Hope this helps!

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
