Nookie1986 [14]1 year ago
4 0

The correct option regarding the error in calculating the length of segment AB is given as follows:

There should have been a subtraction instead of an addition, and the correct length is of 3.5 units.

<h3>Where are points A and B?</h3>

Researching the problem on the internet, it is found that points A and B are on a number line, with coordinates given as follows:

  • A: 1.
  • B: 4.5.

<h3>What is the length of the segment?</h3>

The length of the segment is the absolute value of the subtraction of the endpoints, hence:

L = |4.5 - 1| = |1 - 4.5| = 3.5.

The error is that:

There should have been a subtraction instead of an addition, and the correct length is of 3.5 units.

B is the midpoint of AC. If Ab= x +5 and BC = 2x-11, find the measure of Ab.

__________________________

Measurement of "AC" :

(x + 5) + (2x <span>− 11) ;
________________________

Find the measurement of "AB" [which is: "(x+5)" ]: 
______________________________________________
First, simplify to find the measurement of "AC" :
________________________________________
 </span>(x + 5) + (2x − 11) ;

=  (x + 5) + 1(2x − 11) ;

=   x + 5 + 2x − 11 ;

 → Combine the "like terms" ; 

   x + 2x = 3x ;
   
   5 − 11 = - 6 ;
______________
to get:  3x − 6 ; 
_______________
So,  (x + 5) + (2x − 11) =  3x − 6 ;
_______________________________
Solve for:  "(x + 5)"
_______________________________

We have: 
_______________________________

(x + 5) + (2x − 11) =  3x − 6  ;

Subtract:  "(2x − 11)" ;  from EACH SIDE of the equation ;
                                      to isolate "(x + 5)" on one side of the equation; 
                                      and to solve for "(x + 5)" ;
________________________________________________________
    →  (x + 5) + (2x − 11) − (2x − 11) =  (3x − 6) − (2x − 11) ;
  
         → (x + 5)  = (3x − 6) − (2x − 11) ;
_________________________________________________
  Note:  Simplify:  "(3x − 6) − (2x − 11)" ;

     →  (3x − 6) − (2x − 11)  ;
 
         =  (3x − 6) − 1(2x − 11) ;
 
         =   3x − 6 − 2x + 11 ;
__________________________
   →  Combine the "like terms" :
_____________________________
         +3x − 2x = 1x = x ;
  
          -6 + 11 = 5 ; 
_____________________________
To get:  x + 5 ; 

So we have:
______________________________
 x + 5 = x + 5 ; 
______________________________

So, x = all real numbers.
