Answer:
4
Step-by-step explanation:
(9 x 2/3) x 2/3
9x 2 = 18
18/3 = 6
6 x 2 = 12
12/3 = 4
(9 x 2/3) x 2/3 = 4
 
        
                    
             
        
        
        
R=10 
because 10 divided by ten =1 +4 =5

Cheers.
        
                    
             
        
        
        
Answer:
t ≥ 1.5
Step-by-step explanation:
Lets take time for practicing the piano to be t
The number of hours to practice per week should be at least 6 hours
This is written as t ≥ 6
She already practiced 3 hours this week, thus the remaining hours to practice should be
t ≥ 3
The minimum remaining hours to practice for the remaining 2 days should be
t=3
If these hours are evenly divided, then in a single day she should practice
for t ≥ 1.5
