Answer:
x = 100
Step-by-step explanation:
(x - 20) + x = 180
2x - 20 = 180
<u> + 20 +20</u>
2x = 200
x = 200/2
x = 100
For the mean you add them all up and divide by the ammount of numbers you added. So it would be 118
Using the factor label method, you would set up your ratio like so:
-6,-5,0,5,6 that is the order from least to greatest
