Answer: The cost of each game is $2.50
Step-by-step explanation:
Let's find the equations for each friend:
Friend 1:
Pays $3 for the shoes, and plays 3 games, then if X is the cost of each game, Friend 1 pays a total of:
$3 + 3*X
Friend 2:
This friend buys a soda for $0.50, and he plays 4 games, remember that the cost of each game was X. then this friend pays:
$0.50 + 4*X
And we know that both friends pay the exact same amount, then we can write:
$3 + 3*X = $0.50 + 4*X
And solve this for X.
We need to isolate X, then we can move all the terms with X to the right, and all the terms without X to the left:
$3 - $0.50 = 4*X - 3*X
$2.50 = (4 - 3)*X = X
This means the cost of each game is $2.50

Answer:
48, 55, 56, 68, 74, 78, 83, 85, 99
Mean: 71.77777777777777777..........
Median: 74
Mode: mode is the number seen the most, but there is no repeating values
Range: 51
Step-by-step explanation:
<u>Mean:</u>
add all the values together, and divide by how many values you have, so 646/9= 71.777777777............
<u>Median:</u>
the number in the middle of the sequence
<u>Range:</u>
the difference between the largest and smallest numbers/values.
I hope this helps u pls give a brainliest and a thx ;)
Option (C) -: The hotel floors are parallel to each other, and the elevator moves in a path that is perpendicular to them both.
<h3>What is parallel and perpendicular ?</h3>
In geometry two lines are parallel to each other when they have no intersecting point and the distance between them is constant.
Two lines are perpendicular if they have an intersecting point and they intersect each other at at 90°.
From the given figure we can observe the distance between the floor ceiling of 3rd and 6th floor is constant therefore they are parallel to each other.Now if we imagine the elevator going up and down an imaginary line (meeting line of two elevator doors) would intersect them at an angle of 90°.
∴The hotel floors are parallel to each other, and the elevator moves in a path that is perpendicular to them both.

Answer:
A
Step-by-step explanation:
slope is rise over run 4/1 so the slope is 4 and intercept is 3.
