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 15 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 109^{th} Congress was 434.
There were 30 more Republicans than Democrats. How many members of each party

9. The perimeter of a rectangle is 36 yd. The width is 18
yd less than twice the length. Find the length and the width of the
rectangle.
