Answer:
x = 16
Step-by-step explanation:
9/12 = 12/x
9x = 144
x = 16
 
        
                    
             
        
        
        
25 feet above sea level means she travelled 25 feet to the surface of the sea. She would have to descend (37-25=12) 12 more feet to achieve 37 total feet of travel, so she descended 12 feet below sea level.
        
                    
             
        
        
        
Answer: X=-7
Step-by-step explanation:
Using PEMDAS;
Step 1: Distribute the "3" in the part of the equation "3(x-2)"
3x - 6
Step 2: Consider the equation as a whole with the newly part of the equation from step 1, as it is a part of the equation
Therefore, re-written as,
3x - 6 + 48 = -3x
Step 3: Evaluate the re-written equation
Using basic mathematics skills, we can evaluate the following,
3x - 6 + 48 = -3x ➡ -6 + 48 = -6x ➡ 42 = -6x ➡ -7 = x
As shown, the answer is x=-7.
 
        
             
        
        
        
Yup! We're all pretty good here.
        
             
        
        
        
12000*100/80=15000 coz 12000 is 80% that's why you divide by 80 and multiply by 100
