The document provides classwork and practice problems related to algebraic expressions and one-step equations. New vocabulary terms introduced are coefficient and like terms. Examples are given of adding and subtracting like terms. There are also practice problems for translating expressions, solving one-step equations, and word problems involving algebraic relationships between variables.

2. 2. Like Terms:
Vocabulary:
In algebraic expressions & equations, like terms are terms
that contain the same variables raised to the same power.
Only the coefficients of like terms can be different.
1. Coefficient:
Examples include: 7x x -2x (
1
3
)xy2 -2y2x 6xy2
Adding & Subtracting like terms is just combining the coefficients.
2x2 + 5x =

Translating Expressions

9. 1. Buck has $20 more than Roger. Together they have $90.
How much does each one have?
2. Peter has $6 more than Meg. Chris has $18 more than Peter.
They have $84 all together. How much does each one have?
3. The sum of 3 consecutive numbers is 87. What are the three
numbers?
Key Concept: Always Assign the variable to the smallest, least,
lightest, shortest, etc. Every other number is shown by its
relationship to the variable.
4. Jay worked 6 hours less than May. Together they worked 64
hours. How many hours did each work?
