  • how did you get 44

    

  • @Ultimatepiston 44 is given in the question. It is the average of the 3 numbers 32, 48, and x. You use this to figure out what x is.

  • @PrepInteractive ok i see but how do you get 132

  • @Ultimatepiston To solve for x, you first have to get rid of the denominator 3 on the left side of the equation. To do this, you multiply both sides of the equation by 3. 3 x 44 = 132.
