Answer:
![x=17](https://tex.z-dn.net/?f=x%3D17)
Step-by-step explanation:
![2x+3y=1](https://tex.z-dn.net/?f=2x%2B3y%3D1)
![y=-2-9](https://tex.z-dn.net/?f=y%3D-2-9)
- In order to combine these two equations, an idea you need to keep in mind is finding a way of setting these equations as equal to each other. I saw that each equation shared a common value,
. In this case, we need to isolate
in the first equation so that both equations
.
![2x+3y=1](https://tex.z-dn.net/?f=2x%2B3y%3D1)
![\frac{3y}{3}=\frac{-2x+1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3y%7D%7B3%7D%3D%5Cfrac%7B-2x%2B1%7D%7B3%7D)
![y=-\frac{2}{3}x+\frac{1}{3}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B2%7D%7B3%7Dx%2B%5Cfrac%7B1%7D%7B3%7D)
- With this, we now know that both
and
are equal to
, so we can set them equal to each other.
![y=-\frac{2}{3}x+\frac{1}{3}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B2%7D%7B3%7Dx%2B%5Cfrac%7B1%7D%7B3%7D)
![y=-11](https://tex.z-dn.net/?f=y%3D-11)
![-\frac{2}{3}x+\frac{1}{3}=-11](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B3%7Dx%2B%5Cfrac%7B1%7D%7B3%7D%3D-11)

- Hopefully this answer is correct AND makes sense in terms of how I achieved it. Again, reply to this with any questions or mistakes I made and I'll do my best to answer or fix them.
3.9 x 10 ^-5 is the answer. 0.000039 in scientific notation is 3.9 x 10^-5
I hope this helps you
if one jar is 10 fluids
3 jars ? fluids
?=3.10
?=30
You can use the equation x/700 * 2/100 to get your answer.
700 * 2 = 1400
1400/100 = 14
