You downloaded a video game to your computer. you have 60-minute free trail of the game. it takes 5 minutes to set up the game and 7 minutes to play each level. you want to find out how many levels you can play for free

    X is the number of levels. The rate of change is 7 minutes so that would all together would be presented as 7x. The y - intercept, or in this case the time already wasted setting up the game is 5 minutes. All together that would be 60 = 7x + 5. From there just use algebraic steps to find the number of levels you can reach in 60 minutes.

60 = 7x + 5

55 = 7x

7.86 = x

Since 0.86 isn't a whole level he could only finish 7 levels for free.

Hope this helps :)

use formula for the circle a=3.14

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
