Answer:
it's 4.5
Step-by-step explanation:
you have to find the difference between each number and the mean. then you find the mean of that sum
10
Step-by-step explanation:
you can see it two ways 5×2 or 2×5 better to see it 5×2 cause it's simple 5 then 10 you just add more onto what's the number
Only problem is with the simplifying.
We all know that 5/5 = 1, it is natural to assume (x+a)/(x+a) is also 1, but in some cases where x+a=0, it is undefined. In this equation, where they simplify (x-2) and (x-6), you must say that x is not 2 nor 6 or, you just delete 0/0 which is undefined.
Therefore the only solution would be x=-1
