Answer:
27
Step-by-step explanation:
The expression is 3 + 4z
First, you must know what the value of the variable "z" is.
Because the problem already tells you that z = 6, all you have to do is substitute z with 4:
3 + 4z = 3 + 4(6)
Next, solve using the Order of Operations (P.E.M.D.A.S.).
According to the Order of Operations, multiplication (M) comes before Addition (A). That means you must multiply 4 by 6 first then add the product to 3:
3 + 4(6) = 3 + 24 = 27
