If the<br> average (arithmetic<br> mean) of 2, 7, and x is 12,<br> what is the value of x?
stealth61 [152]

Answer:

x = 27

Step-by-step explanation:

mean is calculated as

mean = \frac{sum}{count}

sum = 2 + 7 + x = 9 + x and count = 3 , then

\frac{9+x}{3} = 12 ( multiply both sides by 3 to clear the fraction )

9 + x = 36 ( subtract 9 from both sides )

x = 27
