Where is the word for "the" in mașina?

In Romanian, "the" is attached to the end of the noun rather than being a separate word. The base word for "car" is mașină (a feminine word ending in -ă). To say "the car", the -ă changes to an -a, giving us mașina.

Why is the word for blue albastră instead of albastru?

Describing words (adjectives) have to match the gender of the noun they describe. Since mașină is feminine, the masculine dictionary form albastru changes to its feminine form, albastră. Also, notice that the adjective comes after the noun in Romanian!

Is it okay to drop the word noi and just say vedem mașina albastră?

Yes! Because the verb vedem already tells us the subject is "we", the pronoun noi is entirely optional. You only need to include it if you want to emphasize that we are the ones seeing the car, as opposed to someone else.
