SOLUTION: The mean of -10, 6, x, 15, and 31 is greater than five. Find the value of x. So I know I would have to do: Mean > 5 but how do I add x into it? Do I do 42x > five and then divid

Question 1017780: The mean of -10, 6, x, 15, and 31 is greater than five. Find the value of x.
So I know I would have to do: Mean > 5 but how do I add x into it? Do I do 42x > five and then divide? Or am I way off?
Thanks for the help!

You can put this solution on YOUR website!
You can't explicitly compute x. You can only compute a range of values for x.



Multiply both sides of the inequality by 5 and simplify.
