Identity property of 0 for addition means a number plus 0 will still be that same number. So -756 + 0 is still -756
Answer:
105
Step-by-step explanation:
Answer:
-6/7
Step-by-step explanation:
5-6x=8x+17
-8x -8x
5-14x =17
-5 -5
-14x =12
/-14 /-14
12/-14 = -6/7
The proportional equation for the the number of gallons of yellow paint, y needed for any amount of blue paint, b is:
<h3>Proportional equation:</h3>
- A <em>proportional equation</em> is modeled by:
![y(b) = ab](https://tex.z-dn.net/?f=y%28b%29%20%3D%20ab)
- In which a is the constant of proportionality.
In this problem, the parameters are:
of a gallon of blue paint, hence ![b = \frac{1}{2}](https://tex.z-dn.net/?f=b%20%3D%20%5Cfrac%7B1%7D%7B2%7D)
of a gallon of yellow paint, hence
.
Then, to find the constant of proportionality:
![y(b) = ab](https://tex.z-dn.net/?f=y%28b%29%20%3D%20ab)
![\frac{4}{5} = \frac{1}{2}a](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7Da)
![a = \frac{8}{5}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B8%7D%7B5%7D)
Hence, the equation is:
![y(b) = \frac{8}{5}b](https://tex.z-dn.net/?f=y%28b%29%20%3D%20%5Cfrac%7B8%7D%7B5%7Db)
