Angie buys 1 software package and 3 months of game play
Kenny buys 1 software package and 4 months of game play
price of each software package = $20
total cost = $117
cost of one month game play = ?
let y is the cost of one month play
Angie buys 3 months game play and paid $20 = 20 + 3y
Kenny buys 4 months game play and paid $20 = 20 + 4y
total cost of both is $117
So the equation becomes,
(20 + 3y) + (20 + 4y) = 117
7y + 40 = 117
7y = 117 - 40
7y = 77
dividing with 7 on both sides, we get
y = 11
so, $11 is the cost of one month game play
Answer:
7.6 inches to make an acute triangle
Step-by-step explanation:
a^2+b^2=c^2
7^2+3^2=c^2
49+9=c^2
58=c^2
Square root both sides
c=7.6 inches
To find the volume,we would first need to find the height of square pyramid, by it's base edge and slant height using Pythagoras theorem:
We can then use the pyramid formula to find the volume:
In this case,the volume will be:
10×_/69×1/3
=27.68874...
≈27.7 units^3

Let the number of cookies that kate eats be ‘n’
kate : n
nacy : 2n-4
avery : 2(2n-4)
n + 2n-4 + 2(2n+4) = 18
7n - 12 = 16
7n = 28
n = 4
kate : 4
nacy : 2x4 - 4 = 4
avery : 2(2x4 - 4) =8
