Answer:

Step-by-step explanation:

The mean is the sum of all the value divided by the number of values.  Set up an expression to match the statement.

\frac{10 + 12 + x +9+18+14+20+23+25+10}{10}=16\\ 10+12+x+9+18+14+20+23+25+10=160\\141+x = 160\\x=19

Answer:

Step-by-step explanation:

First put it in equation form

\frac{(10+12+x+9+18+14+20+23+25+10)}{10} = 16

Add up all the numbers in the brackets

\frac{(141+x)}{10} = 16

Solve for x

141+x = 16 *10\\141+x=160\\x=160-141\\x=19
