Which of the following represents "the average of 171 and x"?

(x + 2)/171
(171 + x)/2
(171 - x)/2

Step-by-step explanation:

We know that the average of any n observations is given by :-

The given observations : x and 171

Sum of observations :

Number of observations : 2

Now, the average of 171 and x is given by :-

Hence, the expression represents the average of 171 and x is .

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
