Writing Equations and Inequalities Lucy’s Linear Equations and Inequalities Jaden’s Phone Plan

What is perimeter? How do we find it? Represent a rectangle that is 2 feet longer than its width and has a perimeter that is 36 feet, algebraically.

How could I represent two consecutive integers algebraically How could I represent two consecutive integers algebraically? What about three consecutive integers? Define the first integer – x Define the second integer – x+1 Define the third integer – x+2

How could I represent two consecutive even integers algebraically How could I represent two consecutive even integers algebraically? What about three consecutive even integers? Define the first integer – x Define the second integer – x+2 Define the third integer – x+4

5 Steps to Writing Equations and Inequalities Draw a sketch (if necessary). Define a variable. Set-up an equation or inequality. Solve the equation or inequality. Make sure you answer the question.

Use the steps on the previous slide to complete Lucy’s Linear Equations and Inequalities and Jaden’s Phone Plan tasks.
