<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)

'nine less than three times a number is negative twenty-one.'
Answer:
f(x) = 2x – 3
f(0) = 2(0) – 3 = -3
f(1) = 2(1) – 3 = 2 – 3 = -1
(f(0) + f(1))/2 = (-3 - 1)/2 = -4/2 (f(0) + f(1))/2 = - 2
