Hank is throwing a surprise party. the party costs $20 per person. create an equation and graph to represent the relationship between the cost of the party and the number of friends attending.

the dependent variable is
a. number of friends (f)
b. cost of party (c)

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
