Answer:
Starting on a platform 2 feet above sea level, dive down to a location that is 18 feet below sea level, and then rise 8 feet.
Step-by-step explanation:
Using the 2 + (-20) + 8 to describe movement relative to sea level ;
2 can be taken as the starting point, positive values represents elevation above sea level ;
2 can be taken as 2 feet platform above sea level ;
- 20 represents distance dived from platform, negative signifies elevation below sea level ; the distance dived relative to sea level is (-20 + platform height)
(-20 + 2) = - 18
8 feets means a final elevation of 8 above sea level (positive value).
Answer:
–3 – (–8) – (–2) = x
Step-by-step explanation:
–3 – (–8) – (–2) = x
Subtracting a negative is adding a positive
-3 +8+2 =x
Starting from left to right
5 +2 =x
7 =x
