How to Write an Algebraic Expression

The video tutorial addresses a standardized math test question requiring the creation of an algebraic expression to represent the total distance a gymnast walked over two days. On Saturday, the gymnast walked x miles, and on Sunday, half of that distance. The tutorial guides through the process of combining these distances into an expression, evaluates multiple-choice answers, and identifies the correct expression as x + x/2.

What is the main task in the given math problem?

• To calculate the speed of the gymnast

• To determine the gymnast's favorite day

• To find the time taken to walk the distance

• To write an algebraic expression for the total distance walked

If the gymnast walked x miles on Saturday, how can the distance walked on Sunday be represented?

• 2x miles

• x + 2 miles

• x miles

• x/2 miles

How do you combine the distances walked on Saturday and Sunday?

• By subtracting the Sunday distance from Saturday

• By dividing the Saturday distance by the Sunday distance

• By adding the distances of both days

• By multiplying the distances of both days

Which option correctly represents the total distance walked by the gymnast?

• x - x/2

• x + x/2

• 2x

• x/2

Why is option D incorrect in representing the total distance?

• It multiplies the distances

• It adds the distances incorrectly

• It subtracts the distances

• It divides the total distance by 2
