If the storybook cost $20, and it was also 2/5 of his money, then 2/5 of his money is $20. In other words:
2x/5 =20.

Multiplying both sides by 5, we get:
2x = 100.

If we divide both sides by 2, then we're left with:
x = 50.

David had $50 at first.

Answer:

In many instances, the lyrics to folk songs came from existing nursery rhymes or poems, and some of the nursery rhymes had variations, depending on region or time. Thus, these folk songs may have lyrics that are slightly different from those you are familiar with.

Therefore, in my opinion, I think that Nursery songs can be considered folk music.

Step-by-step explanation:

Una docena = 12

Por eso:

12 bolígrafos = $ 7848

1 bolígrafo = $ x

Cruz multiplicar

12 bolígrafos × $ x = 1 bolígrafo × $ 7848

$ x = 1 bolígrafo × $ 7848/12

$ x = $654

b) Área de un triángulo ¿9 unidades de base y 6 unidades de altura?

Área de un triángulo =

= 100 × (7.21)
