The subscriber needs to use 363 minutes in a month in order for the second plan to be preferable
What should be sign between the equations for the second option to be better?
The sign between the equation of the first cell phone plan and the second phone plan must less than for the second option to yield more value
Let x be number of minutes of call
Total cost of first option=0.20x
Total cost of second option=39.95+0.09x
For the second option to be better, its value must be less than that of first option
39.95+0.09x<0.20x
39.95<0.20x-0.09x
39.95<0.11x
39.95/0.11<x
x>363

Answer:
x = 6
<u><em>Sorry if this answer is not correct, if it is or is not, please tell me in the comments!</em></u>
Step-by-step explanation:
All of the angles add up to 180 degrees (since it is a triangle), so
(11x - 3) + (7x + 5) + (13x - 8) = 180
Then, combine the like terms.
31x - 6 = 180
Now, out goal is to separate the x from everything. To do that, we need to add 6 to 180.
31x = 186
Then divide by 31.
x = 6
(Feel free to replace x with 6 back in the previous equation to double check it!)
Answer:
Distribute -4 through the parantheses so it can be easier so solve or its either that or collect the like terms
