1. Solve: x - 9 = -2 x = 2. Solve: 3x = -12 x = 3. Solve: -12 = -2x x = 4. Solve: x - (-2) = 5 x = 5. Solve: 5 = -3 + x x = 6. Solve: -12x = -6 x = *Be sure your answer is reduced! 7. Solve: x = 3 x = 5 8. Solve: x = -4 x = -1 9. Solve: x - 9 = -8 x = x= 10. Solve: 3x = -8 *If negative, put negative sign in numerator. 11. Solve: 9x = -81 x = 12. Earth takes 365 days to orbit the sun. Mars takes 687 days. Write and solve an equation to find how many more days, d, Mars takes than Earth to orbit the Sun. 322 more days 1.88 more days 1052 more days 422 more days 13. Earth takes 365 days to orbit the sun. Mars takes 687 days. Write and solve an equation to find how many more days, d, Mars takes than Earth to orbit the Sun. Which equation represents this situation? d - 365 = 687 365d = 687 d + 365 = 687 d ÷ 365 = 687 14. The perimeter of a square is 24 inches. Which equation below represents this? Let s be the length of one side of the square. s - 4 = 24 4s = 24 4 + s = 24 24s = 4 14. The perimeter of a square is 24 inches. Let s be the length of one side of the square. Find the length of a side of the square. 6 inches 20 inches 28 inches 8 inches |
