Q. This equation shows how the total number of pieces Kendra knows how to sing depends on the number of weeks she takes voice lessons.

\newline

p = w + 10

\newline

The variable

w

represents the number of weeks she has taken voice lessons, and the variable

p

represents the total number of pieces she has learned. After

10

weeks of voice lessons, how many pieces will Kendra be able to sing, in total?

\newline

_____ pieces

Identify weeks taken: Step $1$ : Identify the number of weeks Kendra has taken voice lessons, which is $10$ . This $10$ represents the variable $w$ .
Substitute in equation: Step $2$ : Substitute $10$ for $w$ in the equation $p = w + 10$ . So, the equation becomes $p = 10 + 10$ .
Simplify to find total: Step $3$ : Simplify the equation $p = 10 + 10$ to find $p$ . So, $p = 20$ . Hence, Kendra will be able to sing $20$ pieces in total after $10$ weeks of voice lessons.
