Question

Hassan knows how to sing 6 vocal pieces, thanks to his choir class. Now he's about to start private lessons. His teacher says he will learn 2 new pieces each month.

Write an equation that shows the relationship between the number of months Hassan takes voice lessons, x, and the number of pieces he knows, y.
y=

Answer 1

2x + 6

Explanation:

If the number of months Hassan takes voice lessons is x, and he learns two pieces every month, you would multiply the number of months, x, together with the number of pieces he will learn each month, 2, making 2x.

Hassan already knows how to sing 6 vocal pieces, which you would add to 2x.

That makes 2x + 6.
