Which compound inequality can be used to solve the inequality |3x+2|> 7? -7< 3x+2> 7 -7> 3x+2> 7 3x + 2 > –7 or 3x + 2 > 7 3x + 2 < –7 or 3x + 2 > 7

 or  

Step-by-step explanation:

we have

Divide the absolute value inequality into two inequalities

First inequality (positive value)

Second inequality (negative value)

Multiply by -1 both sides

Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

so

therefore

The compound inequality that can be used is

 or  

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
