I'm not sure, 2/4 are correct btw
Answer:
9 - A. If I hadn't gone to bed too late, I (wouldn't be) tired.
10 - C. If it gets hot, the snow (would melt).
11 - B. If I (were) you, I would follow your mum's advice.
12 - B. I would run away if I (saw) a ghost.
Explanation:
9 - The answer is (would't be), because you're using a past-tense form of will.
If you are saying "If I go to bed too late" Then you would be using (I would be) tired.
But since it's a past tense, you would be using (wouldn't be).
10 - The answer is (would melt), because you're using a past-tense form of will.
You use would to preserve the future aspect when talking about the past.
11 - The answer is (were), because you're using a past-tense form of the verb “to be".
"If I (to be) you, I would follow your mum's advice."
So in that way, the answer would be (were).
12 - The answer is (Saw), because you're using a past-tense form.
You use saw when the the action is over, like how it's said I would "run away" if I (saw) a ghost.
Hope that makes sense.
Hope I helped. if so, may I get brainlest and a thanks?
Thank you have a good day. =)
