Answer:
False
Step-by-step explanation:
Let us evaluate the problem using the proper order of operation: 
            4x − 2(5x − 1)
To solve this problem, we use the order of operation called PEMDAS; 
 P - Parentheses
 E - Exponents 
 M - Multiplication
 D - Division 
 A - Addition
 S - Subtraction
Now, since operations inside the parentheses are of the utmost priority, let us solve this; 
              4x − 2(5x − 1)
             = 4x - 10x +2 
             = -6x + 2  or 2 - 6x 
We see that the solution give is false. 
 
        
                    
             
        
        
        
The answer is that my dad paints twice as fast as I do I paint 3/4 in 30 min. but my dad does it in 15 min. so he paints 2 time quicker then i do 
        
                    
             
        
        
        
1+8n=13+6n
1+8n=13-6n
   -6n
1+2n=13
-1       -1
2n=12
2n divided by 2... 12 divided by 2 = 6... n=6
