If the mean of the four numbers 2x and 12 is 10, then x is

4

Step-by-step explanation:

The mean of 2x and 12 is (2x+12)/2, so we get the equation:

(2x+12)/2 = 10 =>

x+6=10

x = 10-6 = 4

* Your question states four numbers, but you write only two... the answer could be wrong because of that.

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope
