Final answer:
The average age of the five men is calculated as (5x + 32) / 5. To identify the oldest person, we need the value of 'x'. However, we do know that the eldest person's age is given by the expression (3x - 6).
Step-by-step explanation:
To find the average age of the 5 men, we first need to express all their ages in terms of the variable x. The ages given are 4, 10, 24, x, and (3x-6). To get the average, we add up all the ages and divide by the number of individuals, which is 5. The sum of the ages is (4 + 10 + 24 + x + 3x - 6), which simplifies to (5x + 32).
The average age is then (5x + 32) / 5.
To determine who is the oldest person, we compare the ages. Since 4, 10, and 24 are constants, the age that will vary is x and (3x - 6). The person with the age (3x - 6) will always be older than the one with the age x for any positive value of x. To find the specific ages, we would need the value of x.
Without additional information, we cannot calculate a numerical average or identify the exact oldest person, but we can say that the oldest person's age is represented by the expression (3x - 6).
