| 25 Questions
Note from the author:
A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.
The outlined content above was added from outside of Formative.

Review Lesson 3-1: Define a variable and write an inequality to model the situation.

A hummingbird migrates more than 1850 mi.
Let m represent the distance in miles that a hummingbird migrates; m ≥ 1850
Let d represent the distance in miles that a hummingbird migrates; d > 1850
Let h represent the distance in miles that a hummingbird migrates; h < 1850
