What inequality represents the condition 1<x<7?  Pick:  A) |x|<3  B) |x+5|<4  C) |x-1|<9  D) |-4+x|<3  E) |3+x|<5
1&lt;x&lt;7 represents segment with   length:   7-1= 
<gadget id="calculator">  7-1</gadget>
<output>6</output>
6   center:   (7+1)/2= 
<gadget id="calculator">  (7+1)/2</gadget>
<output>4</output>
4   For any |x-a|&lt;b a is a center and b is a half of length. So, |x-4|&lt;6/2 represents our inequality (answer |-4+x|&lt;3)
<result>D</result>
What inequality represents the condition 1<x<7?
