  1. Monday April 4th Quarterly Assessment will be on April 6th and 7th

  2. Name- ____________________________ Quarter 3 Review Warm-Up #1 DIrections: Show your work on each question. These are a review from this quarter and these questions will be similar to the Q.A. The area and one side length is given for the rectangle below. Write the correct side length to the missing side of the rectangle. What are the coordinates (x,y) of the solution to the system of equations? Show your work and write your answer here. (___,___) y= 2x +3 y= 4x -1 Simplify the following: 39_ 37 = 1 = 33 3-7 x 35 = units Area = x12 sq. units X7 units

  8. 1x1x1 = 1 2x2x2 = 8 3x3x3 = 27 4x4x4 = 64 5x5x5 = 125 6x6x6 = 216 Cubing a number means multiplying it by itself three times. Since 6x6x6 = 216, each side has a length of 6 units. Therefore, each side is a square, so one side is 6x6 or 26 square inches.

  9. Cubing a number means multiplying it by itself three times. Since 4x4x4 = 64, each side has a length of 4 inches. 1x1x1 = 1 2x2x2 = 8 3x3x3 = 27 4x4x4 = 64 5x5x5 = 125 6x6x6 = 216

  10. Square root √225 x x x = 225 x = 15

  11. What is the unknown side length of the rectangle? A = x9 x6

  12. What is the unknown side length of the rectangle? A = x9 x3 x6

  13. What is the unknown side length of the rectangle? A = x13 x8

  14. What is the unknown side length of the rectangle? A = x13 x8 A=l w x13 = x8 x x5 final answer 5

  15. Consider the following system of two equations. y = 3 + 4x y = -x - 2 What are the coordinates (x,y) of the solution of equations?

  16. Consider the following system of two equations. y = 3 + 4x y = -x - 2 What are the coordinates (x,y) of the solution? 3 + 4x = -x - 2 +x +x 3 + 5x = - 2 -3 -3 5x = -5 5 5 x = -1 y = 3 + 4x = 3 + 4(-1) = 3 + -4 = -1 The solution is (-1, -1)

  17. Consider the following system of two equations. y = 2x + 33 y = 9x - 2 What are the coordinates (x,y) of the solution of equations?

  18. Consider the following system of two equations. y = 2x + 33 y = 9x - 2 What are the coordinates (x,y) of the solution of equations? 2x + 33 = 9x -2 -2x -2x 33 = 7x -2 +2 +2 35 = 7x 7 7 x = 5 y = 2x + 33 y = 2(5) +33 y = 10 +33 y = 43 Final answer: (5,43)

  19. Mrs. Owens and Mrs. White selling candy for the math club. Students can either buy M&M’s and Jolly ranchers. Mrs.Owens sold 20 bags of M&M’s and 80 bags Jolly Ranchers for a total $400. Mrs. White sold 1 bags of M&M’s and 1 bags Jolly Ranchers of a total $11. The system of equations shown can be used to represent the situation. 20m + 80j = 400 m + j = 11 Solve the system of equations. What does the solution represent in this context?

  21. A paper company needs to ship paper in both large and small boxes. Small boxes, when full, weighs 35 pounds. Each full large box weighs 65 pounds. A total of 22 boxes of paper were shipped weighing 1040 pounds all together. Determine how many of each size box were shipped. The system of equations shown can be used to represent the situation. 35s + 65L = 1040 s + L = 22 Solve the system of equations. What does the solution represent in this context?
