Answer:
n = -7
Step-by-step explanation:
-6n + 3 = 45
        -3     -3

-6n = 42
Divide both sides by -6
42/-6 = -7
n = -7
 
        
             
        
        
        
Answer:
x=47
Step-by-step explanation:
Let's solve your equation step-by-step.
180=x+3x−8
Step 1: Simplify both sides of the equation.
180=x+3x−8
180=x+3x+−8
180=(x+3x)+(−8)(Combine Like Terms)
180=4x+−8
180=4x−8
Step 2: Flip the equation.
4x−8=180
Step 3: Add 8 to both sides.
4x−8+8=180+8
4x=188
Step 4: Divide both sides by 4.
4x4=1884
x=47

Answer:
2nd, 4th and 5th one
Step-by-step explanation:
Hey There!
So remember in order for it to be a proportional relationship it has to be a straight line and it has to go through the origin (0,0) 
The 2nd, 4th and 5th ones are non proportional relationships 
Why? Well because they don't go through the origin
