It says for 15 minus a number (meaning a variable like x or y) divided by 2equalseleven
so 15 - y/2 = 11
For question number 3 it says the insurance company wants 100 dollars in deduction fee and then it will pay 80 percent or 0.8 of the medical costs. so we get
0.8(960- 100)
The reason why we subtract 100 is because we paid the insurance company 100 dollars, so that is our own money going to the medical bills.
Because the number of sides is 6 so the s go interior angles is 720. So if u want to get x u need to sum up the rest of the angles anf subtract from 720 giving an answer of 130
