Question

If the mean of 2 3 x and 5 is 4,find x​

Answer 1

the missing number is 6

Explanation:

To find the mean, add up all the numbers and divide by the number of numbers

( 2+3+x+5) /4 = 4

Combine like terms

(10+x)/4 =4

Multiply each side by 4

10+x = 16

Subtract 10 from each side

x = 6
