Answer:

D

Step-by-step explanation:

A:

25d - 58 = 234

Add 58 to 58 and 234

25d = 292

Divide 25 from both sides

d = 11

A is incorrect because you need to subtract the pages that have been read.

B:

25d + 58d = 234

Combine Like Terms

83d = 234

Divide 83 from both sides

d = 83

B is incorrect because 58 pages aren't days, those are the pages read so this equation is overall incorrect.

—

C:

25 + 58d = 234

Subtract 25 from both sides

58d = 209

Divide both sides by 58

d = 3.603 and so on

C is incorrect because, again, 58 isn't the days its the pages read.

—

D:

25d + 58 = 234

Subtract 58 from 58 and 234

25d = 176

Divide 25 from both sides

d = 7.04

D is the correct answer because 25 is the days and 58 is the pages read. You subtracted 58 from each side, making the number of pages in the book go down because you read those pages. You also divided 176 (the pages left) by the days, so 7.04 is your answer. 7 is the answer rounded down. D is your answer.
