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 between the two teams?
a) 2x-5
b) 2x+5
c) 2x-19
d) 2x+19

D) 2x+19

Step-by-step explanation:

Given : During a walkathon,

Total distance traveled by Team A = 6x+12 miles and

Total distance traveled by Team B = 4x-7 miles.

Now, the difference in miles between the two teams = Total distance traveled by Team A - Total distance traveled by Team B

 [∵ (-)(-)=(+)]

Hence, the  difference in miles between the two teams = 2x+19

Thus , the correct answer is D) 2x+19 .

the correct answer is 1: 2
