Answer:
* (USTED) Señora Carmen usted es la siguiente en pasar al consultorio.
* (TÚ) Ramiro tú juegas muy mal baloncesto.
Explanation:
When we use in a USTED conversation, we do it to refer to a second person in a formal language with great respect, be it because they are older than us or because it is a formal situation. When we use TÚ in a conversation, we do it in an informal setting with people we trust.
