Not sure I understand this but
5x+2=0
5x = -2
x = -2/5
Or
x = -.4
Answer:
![x=-16](https://tex.z-dn.net/?f=x%3D-16)
Step-by-step explanation:
![4-\frac{1}{4}x=8](https://tex.z-dn.net/?f=4-%5Cfrac%7B1%7D%7B4%7Dx%3D8)
Subtract 4 from both sides:
![4-\frac{1}{4}x-4=8-4](https://tex.z-dn.net/?f=4-%5Cfrac%7B1%7D%7B4%7Dx-4%3D8-4)
![-\frac{1}{4}x=4](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B4%7Dx%3D4)
Multiply both sides by -4:
![\left(-\frac{1}{4}x\right)\left(-4\right)=4\left(-4\right)](https://tex.z-dn.net/?f=%5Cleft%28-%5Cfrac%7B1%7D%7B4%7Dx%5Cright%29%5Cleft%28-4%5Cright%29%3D4%5Cleft%28-4%5Cright%29)

Answer:
![d=226.2m](https://tex.z-dn.net/?f=d%3D226.2m)
Step-by-step explanation:
From the question we are told that:
Rotational Speed ![N =450rpm](https://tex.z-dn.net/?f=N%20%3D450rpm)
Time ![T=2min=>120sec](https://tex.z-dn.net/?f=T%3D2min%3D%3E120sec)
Radius ![r=4cm=>0.04m](https://tex.z-dn.net/?f=r%3D4cm%3D%3E0.04m)
Generally the equation for Distance Traveled is mathematically given by
![d=\omega*2\pi r*T](https://tex.z-dn.net/?f=d%3D%5Comega%2A2%5Cpi%20r%2AT)
![d=450*2*\pi*0.04*2](https://tex.z-dn.net/?f=d%3D450%2A2%2A%5Cpi%2A0.04%2A2)
![d=226.2m](https://tex.z-dn.net/?f=d%3D226.2m)
Answer:
a) x = -6
Step-by-step explanation:
5x - 14 = 8x + 4
-14 = 3x + 4
-18 = 3x
x = -6
Answer:
