Answer:
z=7
Step-by-step explanation:
Combine like terms: 2z=14
Reduce the greatest common factor on both sides of the equation z=7
answer: z= 7
 
        
                    
             
        
        
        
<u>Given</u>:
The given figure shows the intersection of the two lines.
The angles formed by the intersection of the two lines are (3x - 8)° and (2x + 12)°
We need to determine the equation to solve for x and to find the value of x.
<u>Equation to solve for x:</u>
Since, the two angles (3x - 8)° and (2x + 12)° are vertically opposite angles and the vertical angles are always equal.
Hence, we have;

Thus, the equation to solve for x is 
<u>Value of x:</u>
The value of x can be determined by solving the equation 
Thus, we have;

      
Thus, the value of x is 20.

Answer:
64*(1/4)^x
Step-by-step explanation:
64 is the starting number because it is given, and x represents how many rounds there are. 1/4 represents how much of the teams remain after each round.
