If a = 4, what is the value of the expression 12-a/4 ? A. 1/2 B. 4 C. 11 D. 12

Vocaloid:

they tell you that a = 4 so you can simply substitute 4 for a into the equation as a result you get 12-4/4. apply order of operations to solve this. since division comes before subtraction, complete the division part (4/4) first, then the resulting subtraction problem.
