Answer:  The number is:  349 .
______________________________
Explanation:
____________
Let "x" represent the number we wish to find:
____________________________
Given: "When a number ("x") is divided by "13", the remainder is "11".
________________________________
As such,
_________________
 → x = 13p + 11 ;
_______________________
Given: "When the same number ("x") is divided by "17", the remainder is "9".
As such: 
______________________
 → x = 17q + 9
________________________
Since x = 13p + 11 ; and x = 17q + 9 ; 
___________________________
 → 13p + 11 = 17q + 9 ;    → Subtract "13p" and subtract "11" from EACH side of the equation;
__________________________

 → 13p + 11 − 13p − 11 = 17q − 13p + 9 − 11 ; 

to get: 

___________________________________

→ 0 = 17q − 13p − 2 ; ↔ 17q − 13p − 2 = 0 ; 

→ Add "2" to each side of the equation; 

  → 17q − 13p − 2 + 2 = 0 + 2 ;

  → to get:  17q − 13p = 2 ; 

_____________________

Now, solve for "q", by isolating "q" on one side of the equation:

______________________

→ We have: 17q − 13p = 2 ; 

→ Add "13p" to EACH side of the equation:  17q − 13p + 13p = 2 + 13p ;

→ to get: 17q = 2 + 13p ;

→Now, divide EACH side of the equation by "17"; to isolate "q" on one side of the question, and to solve for "q" ;

____________________________

→  17q / 17 = (2 + 13p) / 17 ;

 → q = (2 + 13p) /17

The  value of "p" for which "[(2 + 13p) /17]" i<span>s a whole number is:
 "26" (p = 26) ;  How do we get this?  We know that "q" should be greater than "1", so we can start with "p = 2";  we get: 13*p = 13*2 = 26, which happens to be a whole number, "26", at the lowest possible value of "p". So we do not have to work with more complicated methods.
</span><span>
___________________
So, since we have: 
___________________
</span>x = 13p + 11 ;  

→ We can plug in our value of "26" for "p", and solve for "x" ;

→ x = (13*26) + 11 ; 

→ x = (338)  + 11 ; 

→ x  = 349;  which is our answer.

_____________________________

Let us check our answer.

_____________________

Given: 

<span>"When a number is divided by 13 the remainder is 11."

So, when 349 is divided by 13, is the remainder, "11"??
(i.e. 349 </span>÷ 13 =? a whole number value PLUS (11/13)???

→ 349 ÷ 13 = 26.8461538461538462 ; 

and: 11/13 = 0.8461538461538462 ; so, YES!
_________________________________________
When 349 is divided by 17, is the remainder "9"?
(i.e. does 349 ÷ 17 = a whole number value, PLUS (9/17)??
___________________
→ 349 ÷ 17 = 20.5294117647058824 ;

→ 9 ÷ 17 = 0.5294117647058824; so, YES!

A South African citizen wants to migrate. To which of the following places is the citizen MOST likely to migrate?
Temka [501]

Most likely to migrate to would happen to be 70 miles away with a population of 7000 because no one likes overcrowded places with barely little to no walking space so D. and A. are out of the question

and for options B. and C. they were a little harder to make out becuase they both seemed legit at first but when you realize it 1500 is really far thats like moving from end to end on that country just about anyways so i went with option choice B.

if this helps mark brainliest
