During a walkathon, Team A walked a total of 6x+12 miles and Team B walks a total of 4x-7 miles. What is the difference in miles
Diano4ka-milaya [45]

The right answer is Option D.

Step-by-step explanation:

Distance of Team A = 6x+12

Distance of Team B = 4x-7

Difference between two teams means subtraction, therefore, subtracting the distance of Team B from Team A;

(6x+12)-(4x-7)\\6x+12-4x+7

Combining alike terms;

6x-4x+12+7\\2x+19

The difference between two teams is 2x+19.

The right answer is Option D.
