Answer:
5 batteries.
Explanation:
"How many batteries lasted more than 5 1/2 hours?" which means it's counting not only 5 1/2, but 5 3/4 and 6 1/4
 
        
                    
             
        
        
        
Answer:
t=2x+ 2
Step-by-step explanation:
x is every phone call 2 is how many minutes she spends on each call The other 2 is the 2 minutes she already spended
 
        
                    
             
        
        
        
1/2 would work for the blank space
because as shown in the image you could relate it to a whole for each one and put it to 100 to figure out what the blank could be
the 0.20 can be converted to 1/5 so that way you can put everything into the 100 group
 
        
        
        
To factor this quadratic equation into double brackets, you need to find two numbers that add together to equal 10, but also multiply to give you 9. These two numbers can be identified as 1 and 9, which will be the numbers you place in your parentheses as follows:
(x+1)(x+9)
