C. Directions: Copy the expressions below. Then encircle the variables and box the constant term in each expression.

1. 30 + n

Answer: $\boxed{30} + nderline{\bold{n}}$

2.15 (r – s)

Answer: $\boxed{15} (nderline{\bold{r}} - nderline{\bold{s}})$

3.4 × 5 + 5z

Answer: $\boxed{4}\times\boxed{{5}} + 5nderline{\bold{z}}$

4.18c – 4d + 6

Answer: $18nderline{\bold{c}} - 4nderline{\bold{d}} + \boxed{6}$

5. 3y + s – 20

Answer: $3nderline{\bold{y}} + nderline{\bold{s}} - \boxed{20}$
