The rules for a book reprt say that the report should have 300 words with an absolute deviation of at most 20 words. write and solve an absolute value inequality that represents the acceptable number of words.

Inequality:

Inquality solved:  

Step-by-step explanation:

You need to remember the meaning of the inequalities symbols:

: Less than.

: Greater than.

: Less than or equal to.

: Greater than or equal to.

Let be "x" the acceptable number of words.

Knowing that the resport should have 300 words with an absolute deviation of at most 20 words, you can write the following bsolute value inequality:

In order to solve it, you need to sep up two cases.

Case 1. The expression is positive:

Solve for "x":

Case 2. The expression is negative:

Solve for "x":

Therefore, you get:

no, because the sides are not congruent
