0.071428571428571 is that what your asking
One bag of soil is 5/8 pounds.
you have 16 of them.
just multiply 16 by 5/8.
you could just type it into your calculator, or you could do it the long way:
![16 * \frac{5}{8} \\ \frac{16*5}{8} \\ \frac{8*2*5}{8} \\ 2*5\\10](https://tex.z-dn.net/?f=16%20%2A%20%20%5Cfrac%7B5%7D%7B8%7D%20%5C%5C%20%5Cfrac%7B16%2A5%7D%7B8%7D%20%5C%5C%20%20%5Cfrac%7B8%2A2%2A5%7D%7B8%7D%20%5C%5C%202%2A5%5C%5C10)
she has 10 pounds of potting soil.
Answer:
A
Step-by-step explanation:
We have the two functions:
![f(x)=-4x+3\text{ and } g(x)=3x^2+2x-4](https://tex.z-dn.net/?f=f%28x%29%3D-4x%2B3%5Ctext%7B%20and%20%7D%20g%28x%29%3D3x%5E2%2B2x-4)
And we want to find (f+g)(x).
Note that this is the same thing to f(x)+g(x). Therefore:
![\begin{aligned} (f+g)(x)&=f(x)+g(x) \\ &=(-4x+3)+(3x^2+2x-4) \end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%20%28f%2Bg%29%28x%29%26%3Df%28x%29%2Bg%28x%29%20%5C%5C%20%26%3D%28-4x%2B3%29%2B%283x%5E2%2B2x-4%29%20%5Cend%7Baligned%7D)
We simply substituted them for their equations.
Simplify. Combine like terms:
![=(3x^2)+(-4x+2x)+(3-4)](https://tex.z-dn.net/?f=%3D%283x%5E2%29%2B%28-4x%2B2x%29%2B%283-4%29)
Add:
![=3x^2-2x-1](https://tex.z-dn.net/?f=%3D3x%5E2-2x-1)
Hence, our answer is A.
