In Spanish, the phrases regularly have the next order:

Article / Noun / Adjective

By this reason, in all of the phrases I put the adjective at the end, and the noun in the middle. By other side, you must pay attention that the adjective agree with the noun, how you can see in the answer, I show you how, when it's a masculine noun, finished in vowels as "o," the adjective finishes in a masculine form too ("o" in the exercises), by last, when the noun ends in a feminine form, the adjective finishes in a femenine form too (in the exercise you can see the noun and the adjective finishes in "a").
