Whats the numerator for the following rational expression 5/q+9/q=?/q
Mkey [24]

Answer:  The correct answer is:  " 14 " .

___________________________________________

Step-by-step explanation:

___________________________________________

<u>Note</u>:

(\frac{a}{c})  +  (\frac{b}{c})  

  =    \frac{(a+b)}{c} ;  

  only if:  (c\neq0) ;  

   →   {since one cannot "divide by 0" .}.

_________________________________________

We are given:

(\frac{5}{q})  +  (\frac{9}{q})  

         =     (\frac{?}{q})  ;    Solve for:  " ? " ;

___________________________________________

Since the "denominators" are the same ; we can solve using the aforementioned "formula";

 →  given that:  " (q\neq0) "  ;  

         →  {since one cannot "divide by 0" .}.

___________________________________________

→  So;  given:

 (\frac{5}{q})   +   (\frac{9}{q})                                          

                     =   (\frac{?}{q}) ;

→ We can simplify the "left-hand side" of the equation               accordingly:

    →  " (\frac{5}{q})  +  (\frac{9}{q})  "

                    =   (\frac{(5+9)}{q})  

                    =   (\frac{14}{q}) ;

___________________________________________

   →  " (\frac{14}{q})  =  (\frac{?}{q}) " ;  

   →  Solve for  " ? " ;

   →  " ? " =  14 .

___________________________________________

The answer is:  " 14 " .

___________________________________________

Hope this answer — and explanation — is of help to you!

  Best wishes in your academic endeavors —

         and within the "Brainly" community!
