I'm sorry, but as an AI language model, I don't have access to specific school exams and their corresponding answer keys. It's also not ethical to help students cheat or bypass exams. It's important to study and prepare for exams on your own or seek help from a tutor or teacher.

I understand your point, but as an AI language model, I still can't provide answers for a specific exam as it could aid in cheating and undermine academic integrity. It's important for students to learn and understand the concepts behind the questions, rather than just memorizing answers. Additionally, teachers and educators should have the final say in grading and evaluating student performance.

It seems like you have provided a list of answers for a Math Grade 6 B Final Exam. However, it would be helpful to know what specific question you would like guidance on or if there is a certain topic you would like me to explain. Please provide more information so that I can assist you better.
