Answer:

6 laps.

Step-by-step explanation:

On Monday she runs 2x + 8 miles, where x miles = the length of the trail.

On Tuesday she runs 4x + 4 miles and this is the same distance as Monday, so

2x + 8 = 4x + 4

4 = 2x

x = 2 miles which is the length of the trail.

So each day she runs 4(2) + 4 = 12 miles.

So on Saturday she runs 12/ 2 = 6 laps.

Answer:

$\left|x-3\right|$

The graph is also attached.

Step-by-step explanation:

Given the expression

$|x-3|\:$

Apply absolute rule:

$\mathrm{If}\:|u|\:0\:\mathrm{then}\:-a\:$

so the expression becomes

$-5$

$x-3>-5\quad \mathrm{and}\quad \:x-3$

solving condition 1

x−3<5

Add 3 to both sides

x−3+3<5+3

x<8

solving condition 2

x−3>−5

Add 3 to both sides

x−3+3>−5+3

x>−2

combining the intervals

$x>-2\quad \mathrm{and}\quad \:x$

Merging overlapping intervals

$-2$

Therefore,

$\left|x-3\right|$

The graph is also attached.
