02.07 Literal Equations
Essential Questions
How can you solve linear equations and inequalities in one variable, including equations with coefficients represented by letters?
How can you rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations?
In the equation: "distance equals rate times time? ____________________ is the most important part. d=(r)(t)
In d=(r)(t) the more efficient way to evaluate r is to__________________ it from the rest of the equation first.

02.05 Inequalities
Essential Questions
How can you create inequalities in one variable and use them to solve problems?
How can you solve linear inequalities in one variable?
An?inequality?means the value of the variable is not equal to one number (like in equations), but instead may be greater than or less than a number.
There are four primary symbols you need to know when working with inequalities.
Indicate what type of circle goes with each inequality symbol
> Greater than ______________
< Less than _______________

02.02 Two-Variable Equations
Essential Questions
How can we create equations in two or more variables to represent relationships between quantities?
How can we represent constraints by equations or inequalities and interpret solutions as viable or nonviable options in the model?
