Answer:
   x = 3.6
Step-by-step explanation:
The angle bisector divides the triangle proportionally.
The base segment to the right of the bisector is 6-x, so we can write the proportion ...
   x/6 = (6-x)/4
Multiplying by 12, we get ...
   2x = 3(6 -x)
   5x = 18 . . . . . add 3x
   x = 18/5 . . . .  divide by 5
   x = 3.6

<em>Alternate solution</em>
Since the base of the triangle is given as a left-part and a sum-of-both-parts, we can write the proportion the same way:
   left-part / sum-of-both-parts = x/6 = 6/(6+4)
Then the solution is x = 6(6/10) = 36/10 = 3.6.
Doing it this way avoids having x on both sides of the equation, so makes solving the equation be "one step."

Answer: 6
Step-by-step explanation: The absolute value of -3 is 3 and the opposite of -3 is 3. That means 3 + 3 = 6.
 
        
             
        
        
        
Answer:
Yes it does
Step-by-step explanation:
 
        
             
        
        
        

so 4/5 of A is really 80% of A then.
since a whole A is 100% of A, 100% - 80% = 20%, A is being reduced by 20%, namely 1/5.
