Eliza's book has a total of 357 pages. How many pages does Eliza read on Monday, Tuesday, and Wednesday combined?

204 pages

Step-by-step explanation:

From the above question, we have the variable:

The expression 1/7r +3(1/7r) can be used to determine the number of pages Eliza reads on Monday, Tuesday, and Wednesday combined.

Hence:

r = 357 pages

Hence:

1/7r +3(1/7r)

1/7 × 357 + 3(1/7 × 357)

= 51 + 3(51)

= 51 + 153

= 204 pages

Therefore, the number of pages that Eliza read on Monday, Tuesday, and Wednesday combined is 204 pages
