The mean is the average number meaning that it is all the numbers in a set added together and divided by how many number are in the set. In this case there are 4 numbers (16, 3, whatever number x is, and 5). So, to find out what x is, first you multiple 4 by the known mean which is 9.
4 x 9 = 36
Then you simply subtract 36 from all the known numbers to find x.
36 - 16 - 5 - 3 = 12
So x = 12
<span>The interior and exterior angles add up to 180° (a straight line - eg, a + f = 180°), andThe sum of the exterior angles is 360° (a + b + c + d + e = 360°).</span><span>Question

First expand the equation.
-5e+5+6e = -17
Next, combine the like terms.
e+5 = -17
e = -22
