Final answer:

Given the total of 20 invitations and that 12 are remaining, Kayla has already sent out 8 invitations. The correct equation is X + 12 = 20.

Explanation:

The subject of this question is mathematics, and it is at the middle school level. The question asks us to determine the number of invitations Kayla has already sent.

To solve this, we are given that Kayla has 20 invitations in total to mail out and she still has 12 left. So, we subtract the number of invitations left (12) from the total (20) to find out how many have been sent out. The operation to solve this is 20 - 12.

The correct equation from the options is X + 12 = 20 where X represents the number of invitations already sent. Solving for X, we find: X = 20 - 12, so X = 8. Therefore, Kayla has already sent out 8 invitations.
