Beginning Algebra Departmental Review Sheet

(Beginning and Intermediate Algebra . Lial. Pearson/ Addison Wesley Longman, Inc., Boston, MA: 2008)

Unless otherwise stated, all work should be done algebraically, all work should be shown, and answers should be simplified.
No formula sheets or note cards are allowed for use during the final exam.
Outcomes are from the course outline. Problems here are in the order as presented there .
You may want to work some core 1-5 outcome problems last, so they are freshest going into the final exam.

[Core Outcome 1, Sec 2.1, 2.2, 2.3]
Solve each equation. Check your solution(s).

[Core Outcome 2, Sec 2.4, 2.5, 2.6]
Solve. Show all the steps: i) Read the problem, ii) Assign (Label the unknown: x represents what words, develop a verbal
model), iii) Write an equation , iv) Solve , v) State the answer (as a compete sentence), vi) Check (makes sense?).

5. Find two consecutive odd integers such that twice the greater is 17 more than the lesser.

6. The total number of Democrats and Republicans in the U.S. House of Representatives during the 109th Congress was 434.
