Answer:
r = 15
Step-by-step explanation:
I don't really have an explanation, I'm just good at quick math,
I'm sorry if you wanted an explanation, I would explain but I am really bad at explaining math.
the sum of all the angles in a hexagon is 720°, so:
(4x-5)+117+(3x-3)+(3x+6)+118+(4x-3)=720
4x+3x+3x+4x= 720+5-117+3-6-118+3
14x=490
x= 490/14
x= 35
Cost of one month of game play = $14
Step-by-step explanation:
Angir buys = 1 software package and 2 months of game play
Kenny buys = 1 software package and 1 months of game play
Cost of Software Package = $25
Total cost = $92
Cost of Game play =?
Total Purchase = 2 software packages and 3 months of game play
Writing in equation:
Let software packages = x and months of game play = y
2x+3y=92
If software package cost 25 i.e x=25, then
2(25)+3y = 92
50+3y = 92
3y = 92-50
3y = 42
y = 14
So, Cost of one month of game play = $14

Answer:
(6,1)
Step-by-step explanation:
midpoint = ((x2+x1),(y2+y1)/2)
= (6+6)/2, (-5+7)/2
= 12/2, 2/2
= 6,1
