Answers and reasoning
Reveal the teacher answer key
- $6 per notebook
Unit rate = 12 ÷ 2 = 6 dollars per notebook.
- -6 m; 0 means at sea level
Sea level is the reference. Below is negative and above is positive.
- 8; opposite again -8
-8 and 8 are each 8 units from 0 on opposite sides.
- -2 < 0 < 7/4; use steps of 1/4
Negative -2 is left of or below 0; 7/4 is right of or above 0. Use equal intervals.
- -4/5 < 0 < 7/10; use steps of 1/10
Negative -4/5 is left of or below 0; 7/10 is right of or above 0. Use equal intervals.
