Kim is reading a book with 380 pages. she read 20 pages each day until she reached part 2 of the book. part 2 of the book is 160 pages long. she uses the equation 380−20d=160380-20d=160 to represent the number of days, d, it took her to read part 1. how many days did it take kim to read part 1 of the book? clear submit 8 days 11 days

It take 11 days to read the first part of the book.

Step-by-step explanation:

As I can see the book has two parts, the total of the book is 380 pages and the second part is 160, so the pages of the first part of the book will be:

From this we can see, that the first part will take:

The first part will take 11 days.

Now from the equation proposed in the argument, we can see that we can calculate also the days that the first part took:

Clearing it:

It take 11 days to read the first part of the book.

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
