7th Grade- 3rd Nine Weeks Review #55.4Use theoretical probability to make predictions.
Look at the spinner. Which event has the greatest probability?A. spinning a 5B. spinning an even numberC. spinning an odd numberD. spinning a number that is NOT a factor of 6
3.8Solve contextual problems involving two-step linear equations.
The table shows what Kayla earns each hour doing various jobs. Last week, she earned a total of $121. She baby-sat for 4 hours and did yard work for 3 hours. Use the equation, 4(9) + 3(7) + 8x = 121 to see how many hours she did house cleaning?
2.3Use rational numbers and perfect squares/cubes to solve contextual problems.
