You can put this solution on YOUR website!
I'm not sure what it is about this that makes you think you need our help....
Substituting c=0.5 in each inequality....
0.5 is greater than 50 FALSE
1/2 13 is greater than or equal to 0.5 I don't know what "1/2 13" means....
7.5 is less than of equal to 0.5 FALSE
0.5<-1 FALSE
0.5<2.5 TRUE
-6 is greater than or equal to 0.5 FALSE
0.5 is less than or equal to 1/2 TRUE (they are equal)

You can put this solution on YOUR website! c = .5 is the solution.
c is greater than 50
c = .5 is not greater than 50, so this is not part of the solution set.
NOT
1/2 13 is greater than or equal to c
1/2 of 13 = 6.5, so 6.5 is greater than or equal to c.
6.5 is greater than c = .5, so this is part of the solutoon sert.
7.5 is less than or equal to c
7.5 is not less than or equal to c = .5, so this is not part of the soluton set.
NOT
c<-1
c = .5 is not less than -1, so this is not part of the solution set.
NOT
c<2.5
c = .5 is less than 2.5, so this is part of the solution set.
-6 is greater than or equal to c
-6 is not greater than c = .5, so this is not part of the solution set.
NOT
c is less than or equal to 1/2
c = .5 is the same as c = 1/2, so this is part of the solution set.
based on the analysis above, the foolowing are not part of the solution set.
c is greater than 50
7.5 is less than or equal to c
c<-1
-6 is greater than or equal to c

You can put this solution on YOUR website! Which of the inequalities below does not include  as part of the solution set.
given inequalities:
 => solution: ( , ) and does  include 
 ...=>  => solution: ( ,  ] and does include 
 ...=> solution: ( ,  ) and does include as part of the solution set
 => solution: (, ), and does include as part of the solution set
 => solution: (, ), and does include
 => or ....solution: (, ] , and does  include as part of the solution set
 => solution: (, ], and does include
so,  and does include
and
, , and  does include as part of the solution set
