Answer:
1 ≤ c ≤ 3
Step-by-step explanation:
In order to meet the standard, the chlorine level (c) must be at least 1 part per million (equal to or greater than 1):
1 ≤ c
At the same time, the level also needs to be no greater than 3 parts per million (equal to or lesser than 3)
c ≤ 3
Combining both inequalities yields (in parts per million):
1 ≤ c ≤ 3.
The compound inequality above describes the acceptable range for chlorine levels.
The author of Passage 1 indicates that becoming adept at using the Internet can undermine the ability to think deeply.
<h3>
What according to the author, becoming adept at using the Internet can cause?</h3>
Passage 1's author cites Patricia Greenfield's study, which discovered that people's use of screen-based technologies harmed their ability to acquire knowledge, perform "inductive analysis" and "critical thinking," and be imaginative and reflective.
The author of Passage 1 concludes that people's ability to think "deeply" is hampered by their use of screen-based technologies.
Option A, C, and D are incorrect because the author of Passage 1 does not address how people's health, social contacts, or self-confidence are affected by using the Internet.
The author of Passage 1 suggests that becoming proficient with the Internet can impair one's ability to think deeply.
Therefore, the correct answer is option B) undermine the ability to think deeply.

Answer:
2) 2x = y + 13
Step-by-step explanation:
We have to translate the given information into an equation. We don't know what the numbers are yet, so let the first number be represented by the variable x and the second number be represented by the variable y.
Start by breaking the sentence apart. "2 times the first number" gives us 
. The "is" in the sentence means that equals something, bringing us to 
. Finally, it says "13 more than the second number." 13 more would mean you have to add to the second number, represented by y, so this gives us 
. Put it all together and it is 
.
