Answer 2

Question: After watching some fish 40 feet below the surface of the water, a scuba diver went up 15 feet to explore a coral reef. Use a number line to help you create an equation that shows the location of the coral reef in relation to the water surface.

Answer:

C. -40+15 = -25

Step-by-step explanation:

The diver went down 40 feet underneath the surface, so that would be -40. When the diver went up 15 feet, that would be adding -40 to 15. So, the diver would be going closer to the surface after coming up 15 feet. -40+15 = -25
