Question

5. The mean of 18, 28, x, 32, 14 and 36 is 23. Find the value of x
6. If the mean of x x + 2 x + 4 + 6 and x + 8 is 13, find the value of x​

Answer 1

Step-by-step explanation:

5 . 23=18+28+x+32+14+36/6

23=128+x/6

23*6=128+x

138=128+x

138-128=x

x=10

6. 5x+20=65

5x=65-20

5x=45

x=9
