2. Math Talk Real Life Scenario Miguel has a rock collection of 30 rocks. Most of his collection consists of igneous rocks. There are 15 igneous rocks. The rest are metamorphic and sedimentary rocks. What could the possible number of metamorphic and sedimentary rocks be? x + 15 + y = 30

3. Math Talk x + 15 + y = 30 In your head think: What are some strategies you might try? What do the variables (x and y) used in the problem represent? Is there more than one solution to the problem? Algebraic Thinking and Measurement What could the possible number of metamorphic and sedimentary rocks be?
