Read the basic rules for showing work below BEFORE you start working on the quiz. Each step should show the complete expression or equation rather than a piece of it. Each new step should follow logically from the previous step, following rules of algebra. Each new step should be beneath the previous step. The equal sign, =, should only connect equal numbers or expressions. Solutions to word problems must follow the Requirements for Word Problem Solutions given on page 121 of the Elementary Algebra textbook. Our textbook is full of good models of work shown correctly. If you have questions about showing work, please ask. Did you read the rules for showing work on page 1 of the quiz? If not, please go back to page 1 now and read them. If you do not show work correctly, you will not earn full credit. 1) Two angles are said to be complementary if their sum is 90 degrees. Suppose you have two complementary angles such that the second angle is 5 degrees larger than 4 times the measure of the first angle. Find the angles. 2) Carmen cuts a piece of string into three pieces. The second piece is 3 times as long as the first piece, and the third piece is 4 feet longer than the first piece. If the total length of the string is 39 feet, find the lengths of each of the three pieces. 3) Solve the inequality. Sketch the solution on a number line, then use interval notation to describe your solution. 4) Solve the inequality. Sketch the solution on a number line, then use interval notation to describe your solution. 5) Complete the table of points that satisfy the given equation.
