How can I solve this: |n| ≥ n
valina [46]

|n| \geq n

For n\leq 0

|n| \geq n \Leftrightarrow -n\geq n \Rightarrow 2n\leq0 \Rightarrow n\leq0

For n>0

|n| \geq n \Leftrightarrow n\geq n \Rightarrow 0\geq0\Rightarrow x\in\mathbb{R}

x>0 \vee x\leq 0 \Rightarrow \boxed{x\in\mathbb{R}}

-------------------------------------------------------------

|n| \leq n

For n\leq0

|n|\leq n\Leftrightarrow -n\leq n \Rightarrow 2n\geq 0 \Rightarrow n\geq 0\\&#10;n\geq 0 \wedge n\leq 0 \Rightarrow n=0

For n>0

|n|\leq n \Leftrightarrow n\leq n \Rightarrow 0 \leq 0\Rightarrow n\in \mathbb{R}\\&#10;n\in \mathbb{R} \wedge n>0 \Rightarrow n>0

n>0 \vee n=0 \Rightarrow \boxed{x\geq0}

You have 2\3 of a pizza left from yesterday. You divide it into 4 equal pieces. What fraction of the pizza is each piece?​
romanna [79]
<h3>Answer:  1/6</h3>

====================================================

Explanation:

Let's say for example this pizza had 6 slices to start with. Two-thirds of this is (2/3)*12 = 4 slices. So you have 4 slices left over from yesterday. Then let's say you hand one slice to each of your four friends. Each friend would have 1/6 of the original pizza.
