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:

The definition of a z-score is:

 

z = (X - μ)/σ where X is our given score (33), μ is the distribution's mean (40) and σ is the distribution's standard deviation (9).

 

To calculate the z-score for 33, plug the numbers in:

 

z = (33 - 40)/9 = -7/9 = -.78

 

Hope this helps!

Varvara68 [4.7K]

Answer:

One clay block = x = $2.50 from before.

One mold = y = $4.00

Step-by-step explanation:

Multiply the second one by -2 to get -12x-2y=-38.00

Add these equations to eliminate y:

-12x-2y=-38.00

3x+2y=15.50

Result: -9x+0y=-22.50

9x=22.50

x=$2.50

Hope this helps love. <3 xx
