It is easiest to simply just substitute any of the choices into the original equation and see which one satisfies the equation.
Given the equation: 3 * |5 + x| = 12
Using choice A. x = 7
3 <span>* |5 + 7| = 12
</span>36 =/= 12
Using choice B. x = 1
3 <span>* |5 + 1| = 12
</span>18 =/= 12
Using choice C. x = -9
3 <span>* |5 + -9| = 12
</span>12 = 12
Therefore, the correct answer is C. -9

use the formula V*t=x so if the velocity is 8 2/3 miles per hour and you need to travel 5 1/5 miles then (8 2/3)*t=5 1/5,
so t=(5 1/5)/(8 2/3)= .6 hours
