You could use Pythagoras Theorem to solve this.
All the points are equidistant from the centre of line AB, therefore it is just the same triangle but rotated. I hope this help but I can show you on paper if you don’t understand that answer :)
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
The most used fractions on a number line used before 1 are 1/4, 1/2, 1/3, 2/4, 2/3, and 3/4.
N = 3
Step-by-step explanation: If you do the equation it comes out to n=4
n+3n=12
4n=12
n=3
You have to add the like terms then divide it so the variable is by itself. And whatever you do to one side, you have to do to the other
