## Questions

### Subject: Spanish

How would someone ask "how old are you"? Write the question, and then answer it in Spanish.

When talking about HOW MANY of something, we use the question word: ¿Cuánto/a/os/as? The ending of the question word (o/a/os/as) is determined by the gender of the noun, which in this case is how many YEARS old someone is. We know the Spanish word for "year" is "el año" which is a masculine noun. Since it is how many yearS (plural), we need to use the masculine, plural form of the question word, which would be: ¿Cuántos? This is the first part of our question. In Spanish, when asking how old someone is, it really translates to "how many years do you have." We know at this point that we will begin our question with,"¿Cuántos años?" but this only means "how many years?" We still need the "do you have?"! We know that the verb "to have" is "tener." To correctly conjugate, we have to realize that the subject of the question is "you," or "tú." The tú form of tener is, "tienes." Therefore, our question would be, in its final form: ¿Cuántos años tienes? = How many years do you have, aka, How old are you To answer, all we have to do is say "I have .... years," using the "yo" form of tener: tengo. I am 25, so to answer, I would say: Tengo veinticinco años. Done!

### Subject: Basic Math

If Caroline has 23 marbles, John has 19 marbles, and Mary has 31 marbles, who has the most?(this is under the assumption that triple digits have not been taught - not sure the level of basic math in this criteria).

To figure out who has the most marbles, we can think about 10s places. If we count by 10s, we start with 10, then 20, then 30. So, we know that 30 is bigger than 20 and 20 is bigger than 10. If we look at the number of marbles that the 3 friends have: John 19 Caroline 23 Mary 31 We see that John's number starts with a 1, but Caroline's starts with a 2. So, we know Caroline has more than John. But, we can see that Mary's number, 31, starts with a 3 so it is bigger than Caroline's. Now we know, Mary has the most marbles!

### Subject: Algebra

Solve for x: 3x + 7 = 25

In order to solve for x, we have to get the x by itself on one side of the = sign. To get x by itself, we first need to move the 7. Since this 7 is being added to the 3x, we need to do the opposite of adding (subtracting) in order to take it away. If we take it away from one side, we have to do the same to the other to keep the equation balanced. By removing, i.e. subtracting, 7 from both sides, we get: 3x = 25 - 7, which can be simplified to 3x=18. Now, the x is still not by itself; we need to get the 3 out of its way. Since the 3 is attached to the x, that means it's being multiplied. To "get rid" of anything that is being multiplied, we must do the opposite and divide. By dividing, we get: x = 18/3, which can be simplified to x=6 since 18 is a multiple of 3.
