Answer:
1. Add 6 to both sides, cause that is the inverse of subtraction, so you get 5x = 50 as 6 cancels 6 out.
2. Divide 5 from both sides and get x = 10
 
        
                    
             
        
        
        
Answer:
15/15 aka 1
Step-by-step explanation:
9/15 and 2/5 
keep the 9/15 and then denominator the bottom number has to be the same as the first one so multiply 5 times 3 to get 15 whatever you do to the bottom you have to do to the top so 2 times 3 equals 6.
9/15 and 6/15
9+6 equals 15 
15/15 which then equals 1 
 
        
                    
             
        
        
        
ok. We are given the following equation:

Where:

Since we are asked to determine "H" we will solve for "H" in the equation. To do that we will first multiply both sides by -1:

Now, we will use the following property of logarithms:

Applying the property and having into account that:

We get:

Now we substitute the given value of "pH = 4.5":

Solving the operation:

Therefore, the hydrogen ion concentration of the fluid is 0.000032
