The lowest point in mississippi is sea level at the gulf coast. a hiker is at an elevation of 91 meters above sea level. how far must the hiker descend to reach sea level? write an addition equation to show the change in position,

- 91 meters

Step-by-step explanation:

Sea level is always represented as 0 so if the hiker were to descend to sea level he would go down 91 meters since they are already 91 meters above sea level.

You need to find out how many meters the hiker is from sea level and in this case they are 91 meters above sea level.

You can also write this as an addition problem by saying 91 + -91 = 0

91 is negative since the hiker is descending so they are going down 91 meters.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
