# RATL 3 | Lesson 1 | Explore (Evaluating Expressions)

Find the value of the expressions for the given values of the variable(s).

a) $$\Large \frac{x+(-7)}{-1}$$, when $$x=-3$$

b) $$(3-(-4)q)^2$$, when $$q=3$$

c) $$-5s+(-6)v-3$$, when $$s=2$$ and $$v=7$$

d) $$m(-7-z)$$, when $$m=-5$$ and $$z=-2$$
