The author organizes the text chronologically in order to A. compare this survival story to other accidents B. propose a solution to the sailors' main problem C. show the order in which the events occurred D. describe the effects this event had on shipping

C. Show the order in which the events occurred.

Explanation:

Chronological order is when events are narrated in such a way that they are described or told according to the sequence in which they occurred. This means that they are arranged according to their time of occurrence.

So, when an author organizes a text in chronological order, that means that they are arranged in the order in which they occurred. The ones that occur first will be listed first, followed by the events that come next to that, and so on.

Thus, the correct answer is option C.

simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13
