Answer:

Hi!

To begin solving we need to isolate the variable.

To do that we can subtract 4 from both side

3x -4 = 13 - 4

Simplified it would be

3x = 9

Now we need to continue to isolate the variable.

To do that we divide both sides by 3

3x/3 = 9/3

Simplified it would be

x = 3

A magazine surveyed readers and found that 175 of the 200 teenagers included in the survey spend at least two hours per night on

PIT_PIT [208]

Answer:

It is not accurate because only information from teenagers was used to make the claim.

Step-by-step explanation:

This is the correct answer because they only used the data that pertained to their teen readers. The magazine does not only have teen readers, but has many ages. The statement regarding internet use generalizes it to all readers, not just teens, therefore making its claim inaccurate because the scope of inference is not appropriate for the claim that was made.
