A cell phone plan costs ​$27.80 per month for 800 minutes of talk time. It costs an additional ​$0.06 per minute for each minute over 800 minutes. To get​ e-mail access, it costs ​30% of the price for 800 minutes of talk time. Your​ bill, which includes​ e-mail, is the same each month for 9 months. The total cost for all 9 months is ​$365.76. Write and solve an equation to find the number of minutes of talk time you use each month.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

16

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
