Answer:

keep reading

Step-by-step explanation:

Well... Dario is at -40 feet. So the difference would be 10 feet.  I don't really know how you would write that equation. But I hope this helped.

The elevation of a diver in relation to another diver at an elevation of −30 feet will be ( -30 + 40 ). The difference between the elevation is 10 feet.

A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R." It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.

Given that Dario was scuba diving at an elevation of −20 feet and then descended 20 feet more. Another diver is diving at -30 feet.

The elevation will be calculated as below:-

Elevation = -30 - ( -40 )

Elevation = -30 + 40

Elevation = 10 feet

Therefore, the elevation of a diver in relation to another diver at an elevation of −30 feet will be ( -30 + 40 ). The difference between the elevation is 10 feet.
