Answer:
With the verb have got, we use inversion to make questions, and have/has to build short positive answers or haven't/hasn't to build negative.
1. she/ bike Has she got a bike? Yes, she has.
Since the sentence we want to transform into a question is: She has got a bike, we just change the position of the subject and the verb to make this sentence interrogative.
2. Have I got a new tablet? No, I haven't.
3. Have we got a horse? Yes, we have.
4. Have they got a lot of homework? Yes, they have.
5. Has Anya got a pet? No, she hasn't.
6. Have you got a mobile phone? No, you haven't.
