Answer:
Marisol vendrá al baile a las siete y media de la noche.
Explanation:
Since the dace is at night we assume it's 7:30 pm. And since it hasn't occurred yet we should use future tense. Venir is an irregular verb so the future tense form does't follow standard conjugation, and the correct form is "vendrá" for the third person.
Answer:

tu envuelves los regalos
mirta y estela barren el suelo
Luis saca la basura
mis hermanos y yo limpiamos la cocina
