Answer:
x + 1/3
Step-by-step explanation:
It just basically the average of the three expressions
=> Remember to divide the expressions into 2 groups (the x group which contains x in it, and the numeral group which doesn't contains x)
The x group: (4x + 7x + (-8x)) /3 = x
The numeral group: (5 +(-6) + 2) /3 = 1/3
So the answer must be x + 1/3, not x + 1
(I hope this is helpful)
Answer:
second option
Step-by-step explanation:
the average is calculated as
average = [tex]\frac{sum}{count}[/tex]
= [tex]\frac{4x+5+7x-6-8x+2}{3}[/tex]
= [tex]\frac{3x+1}{3}[/tex]
= [tex]\frac{3x}{3}[/tex] + [tex]\frac{1}{3}[/tex]
= x + [tex]\frac{1}{3}[/tex]
