Jack can complete 3 chemistry problems and 6 math problems in an hour, while Paula can complete 4 chemistry problems and 7 math problems in an hour; together they need to solve 11 chemistry problems and 17 math problems. Set up and solve a system of two linear equations to determine how long Jack and Paula should each work to complete the problems. Discuss whether your answer makes sense. If not, propose a better solution.

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
