Answer:
the answer is 34.75
Step-by-step explanation:
first, you take all 4 values and add them up. (you should get 122.)
second, you take the 122 and divide it bye the amount of values. in this case there are 4 (100,4,12, and 6). you will get 30.5. (the mean)
third, take all 4 values and subtract them by 30.5. (100-30.5__4-30.5__12-30.5__6-30.5) you will get negitives just drop the negitive signs and change them to positves.
last, add the distant values together (you should get 139) and divide it by 4 ( you should get 34.75)
Answer:
x < 10
Step-by-step explanation:

x < 20/2
x < 10
that means the highest value of x will be 9
example: (2*9)-8 = 18-8 = 10, which is less than 12
