The answer is B. <span>{(1, 2), (2,4), (−1, 2), (0,3)} because it's the only answer where the variables for x aren't repeated. For example, x is 3 twice in A, x is 5 twice in C, and x is -4 twice in D. Please mark me Brainliest! :)</span>

Answer:
There would have been three people in the group.
Step-by-step explanation:
This is because if you add 2/3 together until you get that amount, it will add up to having three people. If this sounds confusing, here is a visual thing to help.
2/3+2/3=4/3 which can also equal 1 1/3
1 1/3 + 2/3 =2
you added 2/3 together three times to get two, so three is the answer.
Hope this helps!
80 multiplied by 2 is 160
speed = distance/time
distance = speed * time
d = st
time up the mountain: t
time down the mountain: 6.6 - t
distance each way: d
Up the mountain:
d = st
d = 80t
Down the mountain
d = st
d = 85(6.6 - t)
The distances are equal, so
80t = 85(6.6 - t)
80t = 561 - 85t
165t = 561
t = 3.4
6.6 - t = 6.6 - 3.4 = 3.2
It takes 3.4 hours up the mountain and 3.2 hours down the mountain.
3.4 hours at 85 mph covers the same distance as 3.2 hours at 85 mph.
3.4 hours * 80 mph = 272 miles
3.2 hours * 85 mph = 272 miles
