The Answer would be x=72. Why? Because 

 is your %.  You Cross multiply 240 * 30 = 100x
240 time 30 = 7200. you want x to  be alone so you do 7200 divided by 100 equaling 72. So you get x=72. 
 
        
        
        
Answer:
E 14/15
Step-by-step explanation:
3/5 = 9/15
1/3 = 5/15
 
        
                    
             
        
        
        
If those question marks are supposed to be a radical, then 12 and 13. The square root of 147= 12.12, which puts it between 12 and 13. 
        
             
        
        
        
Since that is a triangle the expression would be b x h  / 2. So 12*12 = 144 / 2 = 72. The answer is 72.
