Answer: 29

Step-by-step explanation:

The total is 144. We know Monday, Tuesday, and Wednesday. It says the same number of pages were read Thursday and Friday. By adding up Monday, Tuesday and Wednesday you should get 86. Now to find out how many need to be read to finish the book you would subtract that from 144. You would then get 58 and divide by 2; giving you 29

Answer: 29 pages.

Step-by-step explanation:

Given :The book has 144 pages.

On Monday Carlos read 27 pages.On Tuesday he read 31 pages .On Wednesday he read 28 pages .

Let x be the number of pages read by Carlos on Thursday then the number of pages read on Friday will also be x.

Then , according to the question , we have

$27+31+28+x+x=144\\\\\Rightarrow\ 86+2x=144\\\\\Rightarrow\ 2x=144-86\\\\\Rightarrow\ x=\dfrac{58}{2}\\\\\Rightarrow\ x=29$

Hence, he read 29 pages on Thursday.
