Question

The average of 4,6,3, x and 9 is 6.find the value of x.

Answer 1

Answer:

this is correct answer

Answer 2

Step-by-step explanation:

To find the average of a set of numbers you first add them together and then divide the sum by the number of values. The equation, in this case, would look like this:

(4+6+3+x+9)/5 = 6

First, multiply both sides by 5 to get rid of the denominator:

4+6+3+x+9 = 30

Combine like terms:

x+22 = 30

Subtract 22 from both sides:

x = 8

Now substitute for x in the original equation to prove this:

(4+6+3+x+9)/5 = 6

x = 8

(4+6+3+8+9)/5 = 6

30/5 = 6

6 = 6

so x = 8
