Answer:

Equation is 3x + 4 = 22

x = 6

Number of weeks she read is 6.

Step-by-step explanation:

Let x be the number of weeks she read.

Total number of books = 22

Each week she reads 3 books.

After x weeks the number of books left unread = 4

Number of books read in x weeks = 3x

Total number of books = number of books read in x weeks + number of books left unread after x weeks.

22 = 3x + 4

3x = 18

x = 6

Hence number of weeks she read is 6.

Maru [420]

Answer:

-8  -6   -3   4

Step-by-step explanation:

In a number line, the numbers on the are lesser than the numbers on the right. In a number line with integers, numbers going to the right from the midline which is 0 is positive and increases as you move to the right. As you move to the left, the numbers are negative and decreases as you move further to the left.

Attached is a picture of how it would look on a number line.
