The answer is: 5 .
_____________________
Explanation: The solution is: m > 5 .
___________________________
GIven the answer choices, m would not EQUAL "5", since m is GREATER THAN 5; or, "m > 5 ".
______________
All the other answer choices: 7; 9, and 11, are all greater than 5; so they all could be solutions. The question asked which would NOT be solution for the value of "m". The answer choice given, "5", would not be a solution.
_____________________________________________________
How do we get: " m > 5 " ??
___________________________
We solve for "m"; or simplify; as follows:
______________________________________________________
Given: 12m − 8 > 52 ; Let us simplify to solve for "m";
__________________________
→ Add "8" to both sides;
_______________________
→ 12m − 8 + 8 > 52 + 8 ;
____________________________________________
→ to get: 12m > 60 ; → Now, divide EACH side of the inequality by "12"; to isolate "m" on one side of the equation; and solve for "m" ;
________________________________________________
→ 12m / 12 > 60 / 12 ;
_______________________________________________
→ m > 5 ;
