Customers of a phone company can choose between two plans for long distance calls. The first plan has a $17 monthly fee and charges an additional $0.08 for each minute of calls. The second plan has an $8 monthly fee and charges an additional $0.13 for each minute of calls. How many minutes of calls Will the costs of the two plans be equal?

180 minutes of calls

Step-by-step explanation:

Let x represent the minutes of calls

The first plan's cost can be represented by 0.08x + 17

The second plan can be represented by 0.13x + 8

Set them equal to each other and solve for x:

0.08x + 17 = 0.13x + 8

17 = 0.05x + 8

9 = 0.05x

180 = x

So, it will take 180 minutes of calls for the plans to be equal.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
