Question

What are the values of the two observations? 6,8,x+2,10, 2x - 1, and 2 is nine

Answer 1

66+8+(x+2)+10+(2x−1)+2=9

\frac{27 + 3x}{6} = 9627+3x=9

27 + 3x = 5427+3x=54

3x = 273x=27

x = 9x=>9

Answer 2

mean = sum of all numbers / total number

so, BY USING ABOVE formula

6 + 8 + x +2 +10+ 2x-1+2 /6 = 9

= 27 + 3x =54

divide by 3

= 9 +x =18

= x =9

by putting ABOVE value,

x+2 = 9+2=11

and

2x-1=18-1=17

it will definitely help u...
