Is this correct how I answered these two questions?

Donde vive presidente de los Estados Unidos?
My answer: El presidente vive en Washington, D.C.

De donde es tu amigo?
Answer: El amigo es de Colombia.

I know I didn't use accent marks-I will put those in, just wanted to make sure of the answer in correct form.
Thank you

For the 2nd, since the question is "tu amigo" is better with Mi amigo.

Sra

Thank you

Yes, your answers are correct!

Here's how you arrived at the correct answers:

1. Donde vive presidente de los Estados Unidos? (Where does the president of the United States live?)

Your answer: El presidente vive en Washington, D.C.

Explanation: The president of the United States lives in Washington, D.C., which is the capital city of the United States. Therefore, your answer "El presidente vive en Washington, D.C." is accurate.

2. De donde es tu amigo? (Where is your friend from?)

Your answer: El amigo es de Colombia.

Explanation: You correctly identified that your friend is from Colombia. "De" is a preposition that means "from," and "Colombia" is the answer to where your friend is from. Therefore, your answer "El amigo es de Colombia" is correct.

Regarding the accent marks, it is worth noting that while they are important for correct spelling and pronunciation in Spanish, they may not significantly impact the meaning of your answers in these particular instances. However, it's always good practice to include correct accent marks for precision and clarity.
