10 is the answer.
You know that there are 4 numbers and you have to add the numbers then divide them by four to get the mean. So all you have to do is reverse the steps, multiply 30 by 4 to get 120, then add 12+50+48 to get 110. Then subtract, 120-110=10. To check if it is correct add 12, 50, 48, and 10 to get 120, then divide by 4 to get 30. And voila, there is the answer. I hope this helped for future problems like this one.
Answer:
A coefficient is the number that the variable is multiplied by.
The variable is the unknown value, often represented by a letter or symbol.
The constant is the number that is not affected by a variable value, hence the term "constant."
Using the logic above, we can conclude that 4 is the coefficient, x is the variable, and -12 is the constant.
