Answer: B
Step-by-step explanation:
Since it is an equilateral triangle, each angle is equal to 60 degrees and all the sides are the same length
Finding x
since the sides are all the same 3x - 8 = 2x -1, so rearrange and solve for x
3x - 8 = 2x - 1
x - 8 = -1
x = 7
x = 7
Finding y
since each angle is equal to 60, 4y - 4 = 60, so rearrange and solve for y
4y - 4 = 60
4y = 64
y = 16
Final Answer
B - x = 7, y = 16
The time taken by the two men will be equal to 26 hours
<h3>What is speed?</h3>
The speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.
here two men are walking at different speeds like
v₁=6 miles per hour
v₂=10 miles per hour
The time taken by them to separated by the distance of 100 miles each so that both of them separated by the distance of 200 miles.
t₁= {100}/{6}=16.66 hours
t₂= {100}/{10}=10 hours
total time taken will be
t₁+t₂=16.66+10=26.66 hours

Answer:
8 people in the original group.
Step-by-step explanation:
Let x be the number of people who were originally present for the dinner that cost $160. Their average cost per person would be:
$160/x
If 2 more people join, there are x+2 people. Ignoring the awkward situation that they apparently did not order any additional food, they agree to share the cost of the dinner. The average cost is now:
$160/(x+2)
We are told that this new average is now $4 less per person.
$160/(x+2) = ($160/x) - $4
$160 = (($160/x) - $4)(x+2)
x = 8 people
