1) Fredricka has a triangular garden bed in her front yard. The measure of the largest angle is 10 less than three times the measure of the smallest, and the measure of the middle angle is 15 more than the measure of the smallest angle. Find the measures of the three angles. Start your work by defining the unknown quantities in terms of a variable. Show all work and write a complete answer, including units. 2) David decided to ride his moped across the country during his 12 week summer vacation. The route he took from Baltimore, MD to Tucson, AZ covered a total of 2315 miles. To keep his mind occupied during some of the long flat stretches of countryside, he often did algebra problems in his head. One day, for example, he determined that his distance from his starting point was exactly 85 miles less than twice the distance remaining until the finishing point. How far was David from the finishing point of his journey when he made that calculation? Start your work by defining the unknown quantities in terms of a variable. Show all work and write a complete answer, including units. 3) Solve the inequality. Write the answer using both set-builder notation and interval notation.

If she invests $8,000 in a savings account paying 6% annual simple interest, at what rate does the remainder of her money need to be invested so that the two investments together yield at least $950 in yearly simple interest? (Set up and solve an inequality to answer this question.) 9) Given the equation below, find four ordered pair solutions by completing the table, showing all work in the space below.
