The time Henry spends commuting to school can be represented by two expressions: Time to school: x - 8y Time from school: 2x - 4y Which expression represents the total time Henry spends commuting to and from school each day?

3x - 12y

-7x - 12y

x + 4y

3x + 4y

Answer: 3x - 12y

Step-by-step explanation:

Hi, to answer this question we have to add both expressions, the times "from" and "to" school.

Total time spent: time to school + time from school

Mathematically speaking:

x - 8y + 2x - 4y

Adding alike terms:

x + 2x - 8y - 4y = 3x - 12y

In conclusion, the expression that represents the total time Henry spends commuting to and from school each day is 3x - 12y.

The answer is 3x-12y because you combine the like terms so 2x+x=3x and - 8y-4y=-12y
