A.
Knurling
B.
Turning
C.
Punching
D.
Grooving
Correct Answer: Knurling
Explanation
To solve for x in the equation (x + 2) / 2 = 19, you can first multiply both sides of the equation by 2 to get rid of the fraction.
2 * (x + 2) / 2 = 2 * 19 x + 2 = 38
Then, you can subtract 2 from both sides to solve for x x = 38 - 2 x = 36
So the value of x that satisfies the equation (x + 2) / 2 = 19 is 36.
