Yolanda needs 5 pounds of ground beef to make lasagna for a family reunion. One package of ground beef weighs 2 1/2 pounds. anot

You need to put the answers into improper fractions.
So 2 1/2 into 5/2 
And 2 3/5 into 13/5
Now your fractions need the same denominator so multiply 13/5 by 2 and multiply 5/2 by 5
You should now have 25/10 and 26/10
Now turn them back into mixed fractions.
2 5/10
2 6/10
2+2=4
5/10 + 6/10 = 11/10 OR 1 1/10
4+ 1 1/10 = 5 1/10
1/10 is your remainder

C=85x+60<br> solve for x
Tatiana [17]
To solve for x:

<span>C=85x+60                  subtract 60 from both sides
</span>
<span>C - 60=85x+60 - 60

C - 60 = 85x              now divide by 85 both sides

(C - 60)/85 = x


So we can write:
x= \frac{C-60}{85}



</span>

I hope that helps!
