Answer:
Part A: x > -60
Part B: 3. <--------o
Step-by-step explanation:
If the researchers explored a deeper depth than -60, that means the depth of the second dive must be more deeper than -60, not equal to it. so x > -60, and deeper depth means more larger negatives, and open circle stands for greater than/less than, so 3. would be the appropriate answer. hope this helps
