9. Mr. Petrash and Ms. Wallace’s classroom closets both contain notebooks, pencils, and calculators. The value of the items inside each closet can be represented by the expressions below. Mr. Petrash: p + 0.5n + 85c + 3 Ms. Wallace: p + n + 85c Write an expression that represents the combined value of the items in both closets. 10. What is the perimeter of the given triangle? a2 + 3a – 7 5a 4a2– a Simplify each expression. 11. 4(f – 2) = 12. 7 – 2(2c – 1) = A#1-1, p. 2 13. -3.2(g + 4) – 5g + 1 = 14. 12 + 2(3v – 4) = 15. 5h – 3(4h – 3) + 2 = 16. 3 + 21 (2x – 12) + 4x = Solve each of the following equations. 17. 3c + 5 = 20 c= 18. 7 – 3a = -14 a = 19. 43 x + 14 = 8 x = 20. -19 = 3m – 1 m =

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
