Angie and Kenny play online video games. Angie buys 1 software package and 2 months of game play. Kenny buys 1 software package
GalinKa [24]

Answer:

The cost of one month of game​ play is $12.    

Step-by-step explanation:

We are given the following in the question:

Cost of software package = $30

Let y dollars be the cost of one month of game play.

Angie buys 1 software package and 2 months of game play.

Angie's cost =

1(30) + 2y = 2y + 30

Kenny buys 1 software package and 4 months of game play.

Kenny's cost =

1(30) + 4y = 4y + 30

Total cost = $132​

Thus, we can write the equation:

(2y+30)+(4y+30) = 132\\6y + 60 = 132\\6y = 132-60\\6y = 72\\\Rightarrow y = 12

Thus, the cost of one month of game​ play is $12.

If angle B is two more than three times the measure of angle C, and angle B are
GalinKa [24]

Set up a system of equations:

B=2+3C

B+C=90

The variable B is already solved, so plug into bottom equation:

2+3C+C=90

2+4C=90

4C=88

C=22

Plug C back in:

B+22=90

B=68

So B is 68 degrees and C is 22 degrees

Hope this helped!
