Answer:
B
Step-by-step explanation:
I believe the answer is B because if we multiply the top equation by 6, we get 48x + 30y = -42, and if we multiply the bottom equation by -5, we get
35x - 30y = 20. So now, if we add it all together, then the positive 30y and negative 30y cancel out aka it equals 0, and thus the variable y is gone, satisfying the requirement that the problem asks for ("Which of these strategies would eliminate a variable...").
I hope this helped, and if it's correct, I'd appreciate if you marked my answer as Brainliest :)
Are you asking the equation or the answer
Answer: It is exactly 85.7142857143
But if you would like it rounded: 85.7
I would go with the second answer.

AB=root (11-3)^2-(10-4)^2
= root 64-36
= root 28 units
