  1. Answer:

    [tex]x = 24[/tex]

    Step-by-step explanation:

    [tex]6 + 10 + x + 20 + 30 = 18[/tex]

    There are 5 numbers that we must add to average out to get 18 so let set this equation up

    [tex] \frac{6 + 10 + x + 20 + 30}{5} = 18[/tex]

    [tex]6 + 10 + x + 20 + 30 = 90[/tex]

    [tex]x = 24[/tex]

  2. Answer:

    24

    Step-by-step explanation:

    18 times 5 is 90 so that means that the given numbers have to add up to 90 (including x)

    so,

    6+10+20+30=66

    90-66=24

    I hope this helps!
