the average of 3 numbers is 12. if one of the numbers is 8 what are the sum of the other 2 numbers i need help asap
Let the variables X & Y represent the 2 missing numbers.
So, (8 + X + Y)/3 = 12
multiply both sides of the equation by 3 to get 8 + X + Y = 36
subtract 8 from both sides of the equation to get X + Y = 28
So, the sum of the 2 missing numbers is 28!
To check 8 + 28 = 36 and 36/3 = 12
Good luck!
