Activity In this activity, you will model a real-world situation with a system of two linear equations. Then you'll use elimination to solve the system. Read this scenario, and then answer the questions that follow. A test is worth a total of 150 points and contains 70 questions. Some of the questions are worth 2 points, and some are worth 4 points. Part A Question The first equation in the system of equations that models this situation is x + y = 70, where x represents the number of 2-point questions and y represents the number of 4-point questions. What is the other equation in the system? Enter the correct answer in the box. Substitute numerical values in the expression for A, B, and C. Part B Question Solve your system of equations from part A using elimination. Then, complete the statement. Type the correct answer in each box. Use numerals instead of words. The test has questions worth 2 points and questions worth 4 points. Self-Evaluation How did you do? Rate your work on a scale of 1 to 5, with 5 as the highest score.
