<p>Can't figure this question out..</p>
<p>It's a number line so i can't exactly type it out..</p>
<p>This one is drawn to scale so I would trust the drawing. "u" is like -.80 and "w" is around -.5. So -.8--.5, you add the negatives to get -.3, take the absolute value of that to get .3. Now let's find the value that is closest to .3. Only "x" can be .3 since it's closest to 0 on the right hand side.</p>
