Answer: 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
[tex]=6x+12-(4x-7)\\\\=6x+12-4x+7[/tex] [∵ (-)(-)=(+)]
[tex]=6x-4x+12+7\\\\= 2x+19[/tex]
Hence, the difference in miles between the two teams = 2x+19
Thus , the correct answer is D) 2x+19 .
Answer6-4 = 2x, 12+7=19 so it will be 2x+19
