The absolute value of x: |x|.
|x| = x if x ≥ 0 <em>examples: |5| = 5; |0| = 0; |8.34| = 8.34; |1/2| = 1/2</em>
|x| = -x if x < 0 <em>examples: |-5| = -(-5) = 5; |-8| = -(-8) = 8; |-1.2| = 1.2;</em>
<em> |-3/7| = 3/7</em>
<em>Therefore</em>

Answer:
9.59
Step-by-step explanation:
You divide 6.85 by 5 to get 1.37, then you multiply it by 7 to get your answer 9.59 :)
Answer:
L=43 and W=22
Step-by-step explanation:
The perimeter of a rectangle is 130 meters. We also know the longest side called the length is 1 less than twice the width or 2w-1. The width is w. To find perimeter, you must use the formula P=2l+2w.
130 = 2(2w-1) +2w
130 = 4w -2 +2w
130 = 6w -2
132 = 6w
132/6 = w
22 = w
So the length is l=2w-1=2(22)-1 = 43
