Answer:
a=12-6b
Step-by-step explanation:
move b and a to their respective sides, getting a = -6b+12
tada :)
First, we have to figure out how much cheese we have total. Do this by adding up all of the various cheeses.
![\frac{2}{3} + \frac{4}{3} + \frac{5}{4} \\ \frac{6}{3} + 1 + \frac{1}{4} \\ 3 \frac{1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%7D%20%20%2B%20%20%5Cfrac%7B4%7D%7B3%7D%20%20%2B%20%20%5Cfrac%7B5%7D%7B4%7D%20%5C%5C%20%20%5Cfrac%7B6%7D%7B3%7D%20%20%2B%201%20%2B%20%20%5Cfrac%7B1%7D%7B4%7D%20%20%5C%5C%203%20%5Cfrac%7B1%7D%7B4%7D%20)
Now to split the cheeses into sections of 1/4 pound each, we have to divide by 1/4, which is the same as multipling by 4
![3 \frac{1}{4} \times 4 = 12 + 1 = 13](https://tex.z-dn.net/?f=3%20%5Cfrac%7B1%7D%7B4%7D%20%20%5Ctimes%204%20%3D%2012%20%2B%201%20%3D%2013)
13 slices total
100(2.25/3)=75%

The answer to your question would be 13.565 or rounded to hundreds would be 13.57
3.4 = -13.6 - 3.4c + 1.7c
3.4 = -13.6 - 1.7c
1.7c = -13.6 - 3.4
1.7c = 17
c = 10
