W = words per minute = 80
t = time in minutes = 30
The total number of words per 30 minutes is w*t = 80*30 = 2400 words

Step-by-step explanation:
First multiply 72 by 10 
because 72 is 72 10s, making it a whole number. 
then add 720 (72 times 10) to 7. 
then all of that over 10. 
then just divide. 
727/10
72.7
this is what you do for all mixed numbers like that one.

Step-by-step explanation:
 
        
                    
             
        
        
        
X³ = 125/27
Cube root both sides to isolate the variable:
∛x³ = ∛(125/27)
x = ∛(125/27)
∛125 = 5, ∛27 = 3
x = 5/3
