This isn’t an equation— equations require an equal sign and a variable of some sort on the other side of that said equal sign. Sorry.
Answer:
1. Amaia es mi Hermana
2. Carlota es mi hermana
3. Maria es mi mamá
4. Felipe es mi Papa
5. Manuel y Anaia son mis abuelos
The answer would be A.
Casa is house/home and it makes the most sense in this sentence :)
Have a good day!
I won't answer the questions for you, but I'll translate what they mean (if you still need help after this, leave a comment (: )
1.) At what hour do they leave the house? (3:00)
2.) What do Inés and Cecilia see? (shoes)
3.) Where did Inés lose the money? (In the sports shop)
4.) Did you return to the store to look for it? (Yes)
(Not sure how well I did on 4, If I remember right "buscarlo" is an example of a reflexive verb.)
