Answer:
The answer to your question is 43.8 mL of acid.
Step-by-step explanation:
Data
Total volume = 362 ml
12.1 % is acid
The Volume of acid = ?
Process
1.- Use the rule of three and cross multiplication to solve this problem.
                 362 ml ------------------- 100%
                     x       -------------------  12.1 %
                     x = (12.1 x 362) / 100
                     x = 4380.2 / 100
                     x = 43.802 ml
2.- Round your answer to the nearest tenth.
                         43.802   only consider the first decimal
                         43.8 mL
3.- Conclusion
     A 12.1% solution of acid has 43.8 mL of acid.
 
        
                    
             
        
        
        
Step-by-step explanation:
You should prolly subtract 2 from both sides first.
So you get, -|2/5x + 3| > -1 2/5
- Add three to both sides
- -|2/5x| = -1 2/5
- Do -1 and 2/5 divided by 2/5 to get -3.5, x > -3.5
One of the answers is x > -3.5 but you need to switch the sign to less than and make the other side the opposite.

You see that, switched the sign and made whats on the right side opposite. So now solve for x again but with this new equation. Also, the parentheses are absolute value signs
Subtract 3 from both sides
-|2/5x| < -1 and 3/5
Divide 2/5 from each side to get x < -4
I hope I'm correct, my bad if I'm wrong
