Answer:
PQ = 3.2
Step-by-step explanation:
 
 
 
 
 
 
PQ = PR - QR 
PQ = 4.8 - 1.6
PQ = 3.2
 
        
             
        
        
        
10x^2y^-2 = 10 x (-1)^2 x (-2)^-2 = 10 x 1 x 1/4 = 10/4 = 2 1/2
        
             
        
        
        
With the equation:
0.15 x = 30
x = 30 : 0.15 = $200
A regular price of TV is $200.
Which could not be used to determine x ( we shall plug in the value 200 ):
A ) 0.15 * 200 = 200 - 30
30 ≠ 170
B ) 0.85 * 200 = 200 - 30
170 = 170 ( correct )
C ) 200 - 0.15 * 200 = 200 - 30
200 - 30 = 200 - 30
170 = 170   ( correct )
D ) 0.15 * 200 = 30
30 = 30  ( correct )
Answer:
A ) 0.15 x = x - 30
