Answer:
![n = 5.67](https://tex.z-dn.net/?f=n%20%3D%205.67)
Step-by-step explanation:
0.3(n-5)=0.4-0.2
0.3(n-5) = 0.2
Dividing 0.3 both side
![\frac{0.3(n-5) }{0.3} = \frac{0.2}{0.3}](https://tex.z-dn.net/?f=%5Cfrac%7B0.3%28n-5%29%20%7D%7B0.3%7D%20%20%3D%20%5Cfrac%7B0.2%7D%7B0.3%7D)
![n-5 = 0.67](https://tex.z-dn.net/?f=n-5%20%3D%200.67)
![n = 0.67+5](https://tex.z-dn.net/?f=n%20%3D%200.67%2B5)
![n = 5.67](https://tex.z-dn.net/?f=n%20%3D%205.67)
Answer:
15 metal post
Step-by-step explanation:
all you have to do is divide 20 into 300
The domain of the function f(x) is where the area under the square root (aka the radicand) is positive or zero. We have to write that the radicand is greater than or equal to zero, so
![\dfrac{1}{2}x-10 \geq 0](https://tex.z-dn.net/?f=%20%5Cdfrac%7B1%7D%7B2%7Dx-10%20%5Cgeq%200)
