The person walked a distance of 120 kilometers in a time 3 hours. (Correct choice: C)
<h3>What is the length of the path covered by a person?</h3>
Herein we have the case of a person walking during a total time of three hours, whose conditions are explained mathematically by the following formula:
x = x / 3 + x / 4 + (x / 3 + 10)
x = (2 / 3) · x + x / 4 + 10
x = (11 / 12) · x + 10
x / 12 = 10
x = 120
The person walked a distance of 120 kilometers in a time 3 hours. (Correct choice: C)

<u><em>Answer: x=-17 and -17=x. *The answer should be the negative sign.*</em></u>
Step-by-step explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
a-c=b-c
subtract by 5 both sides of an equation.
x+5-5=-12-5
simplify.
12+5=17
17-5=12
17-12=5
x=-17 and -17=x
Hope this helps!
Thanks!
Have a great day!
