If w is real then we need ignore negative sign and consider it as a mod value. So the answer will be 2
        
             
        
        
        
Z=22
180-120=60
2x+16=60
2x=44
Z=22
        
                    
             
        
        
        
The average speed is given by:
average speed=(total distance)/(total time)
total time for the first 30 miles was:
time=distance/speed
=30/30
=1 hr
total time for the remaining 30 miles
=30/60
=0.5
hence the average speed will be:
speed=(30+30)/(1+0.5)=60/1.5=40 miles per hour 
        
             
        
        
        
Answer:
Step-by-step explanation:
3) Sales tax rate = 
                          = 8.50 
                         = 9%
4) Rate of commission = 
                                      = 5 %
5) Reduction = 
                     =$ 1500
New price = 5000 - 1500
                = $ 3500
