a man drives x miles the first day,y miles the second day,and z miles the third day. the average mileage per day is
a)(x+y+z)/3
b)(xy+z)/3
C)(xyz)/3
d)3xyz
E)x+Y+Z
What do you think is the answer? Post it and we'll be glad to check it.
i think the answer is a.
You're right! :-)
The average mileage per day is calculated by dividing the total mileage driven over the three days by the number of days.
To calculate the average mileage:
Step 1: Add up the total mileage driven over the three days: x + y + z.
Step 2: Divide the total mileage by the number of days (which is 3): (x + y + z) / 3.
Therefore, the correct answer is option a) (x + y + z) / 3.
