Answer:
6
Step-by-step explanation:
Total number of subsets is given as 

But the subset of a set consists of the proper subsets, an empty set and the set itself. 
Total number of subsets are 64
Therefore,


Comparing both sides

Answer:
36129
Step-by-step explanation:
 
        
             
        
        
        
Given, arc QR is congruent to arc LN and arc OP is congruent to arc VW.
And the expressions for each arc in the diagram also given as:
Arc QR = 2x - y, arc LN = 11 , arc OP= 10 and arc VW=5x+y.
Hence, we will get the system of equations as following:
Arc QR = Arc LN
2x - y = 11 ...(1)
Arc OP = Arc VW
5x + y = 10 ...(2)
We need to find the value of x. So, we can add the equations to eliminate y so that we can solve the equations for x. Therefore,
2x+5x = 11 + 10
7x = 21
 Divide each sides by 7.
 Divide each sides by 7.
So, x= 3
