Answer:
x=3
Step-by-step explanation:
2
x
+
3
=
9
We want to find the variable  
x
, so we have to make it alone. To do so, first subtract  
3
 from both sides of the equation:
2
x
+
3
  
−
  
3
=
9
  
−
  
3
2
x
=
6
Now divide both sides by  
2
:
2
x
2
=
6
2
So the final answer is:
x
=
3
Hope this helps!
 
        
                    
             
        
        
        
Answer:
6 Cubed
=
216
Step-by-step explanation:
6 Cubed
=
216
 
        
                    
             
        
        
        
First you need to turn this into an improper fraction. Then, using your improper fraction, you simplify
        
                    
             
        
        
        
Answer:
0.025 Kg/ cm²
Step-by-step explanation:
if two variables vary inversely, there is a negative relationship between both variables. the increase in one variable leads to a decrease in the other variable
the equation that represents inverse proportion : 
 
 
where b = constant of proportionality 
to determine the answer in this question : 
1. determine constant of proportionality
200 = k / 32 
k = 6400 
2. Determine the amount of pressure using the constant of proportionality
256, 000 = 6400 / pressure 
pressure = 6400 / 256, 000 = 0.025
