One high speed Internet provider has a $39 setup fee and charges $40 per month. Another provider has a $60 setup and charges $30 per month. In how many months will the cost be the
same?

2.1 months

Step-by-step explanation:

Let x represent the number of months

Set up expressions to represent the cost of each Internet provider

40x + 39 will represent the first one

30x + 60 will represent the other

Set these equal to each other and solve for x:

40x + 39 = 30x + 60

10x + 39 = 60

10x = 21

x = 2.1

So, the cost will be the same in 2.1 months

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
