Question

show what you know
ariana ran 6 times around her school building.
then she ran 4 miles home.
her phone told her that she ran 7 miles total.
a. which equation represents this situation?
6 + 4x = 7 \t 6x + 4 = 7 \t 6(x + 4) = 7

Explanation:

Step1: Define the variable

Let \( x \) be the number of miles per lap around the school building.

Step2: Calculate miles from running around the building

Ariana ran 6 times around the school building, so the distance from that is \( 6x \) miles.

Step3: Add the miles ran home

She then ran 4 miles home. The total distance is the sum of these two, so the equation is \( 6x + 4 = 7 \).

Answer:

\( 6x + 4 = 7 \) (the middle option among the given ones)
