Translation: Nosotros tenemos mucha tarea
Primeramente hago muchos deberes
No, you can say "I have a lot of homework." Or "I have to much homework"
"Homework" is always singular, so you would say, "Brian and Emily have finished their homework." If you want a plural to refer to homework from different classes, you can say "homework assignments."
Tengo Deberes
It is not grammatically correct, no. The word is homework. "I have a lot of homework." or "I have homework in several classes."
It sounds unnatural. I'd say no, you can't. Just say "a lot of homework".
Entregar la tarea.
The Spanish is "mucha tarea", which means " a lot of homework" or "a lot of work" in English.
Translation: deberes OR tarea
Muchos deberes. Muuchas tareas.
In what class do you have a lot of homework?= ¿En quéclase tienes mucha tarea?
La tarea en Algebra. That's how it's spelled anyway. Can't help with pronunciation though
