A. Elena read three times as many pages as the number of pages Noah read and she read 27 pages
Suppose Noah read x pages
So Elena will read 3x pages
According to the question
Number of pages Elena read =27
So, 3x=27
So this question can be answered by the equation 3x=27.
B) Lin has 27 stickers. She gives 3 stickers to each of her friends. how many stickers did each friend get?

Total stickers = 27
3x=27
So this question can be answered by the equation 3x=27.
Similarly, the other 2 options can be answered by the equation 3x=27.
Hence, all the questions can be answered by the solution to the equation 3x = 27.
