-2|8-x|-6=-12 \ \ \ |\hbox{add 6} \\
-2|8-x|=-6 \ \ \ |\hbox{divide by (-2)} \\
|8-x|=3 \\
8-x=-3 \ \lor \ 8-x=3 \\
-x=-3-8 \ \lor \ -x=3-8 \\
-x=-11 \ \lor \ -x=-5 \\
x=11 \ \lor \ x=5 \\
\boxed{x=5 \hbox{ or } x=11}

It should be x=11 instead of x=-11, so he is not correct because he made a sign error.

Karen drives straight south on Interstate 405 from the Santa Monica Freeway interchange going 10 miles per hour faster than Meli
natima [27]

Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.

<h3>Equation for speed</h3>

Speed is the ratio of total distance travelled to total time taken. It is given by:

Speed = distance / time

Let a represent Karen speed and b represent Melinda speed, hence:

a = b + 10

a - b = 10   (1)

Also:

a = d₁ / 1

d₁ = a

b = d₂/ 1 hour

d₂ = b

Since they are 108 miles apart, using Pythagoras:

108² = d₁² + d₂²

a² + b² = 11664

(b + 10)² + b² = 11664

b = 71.2 mph, a = 81.2 mph

Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.
