He sum of two numbers is negative twelve​, and one number is five​ less than the other. Using the variables mm​ and nn​ to represent the two numbers, write a system of equations that describe the situation. Enter the equations below, separated by a comma.

mm + nn = -12

mm - nn = 5

Step-by-step explanation:

two equations can be derived from the question

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
