Timothy bought 10 cookies for $5.00. Let x represent the number of cookies purchased, and let y represent the total cost.

Graph the line that represents the proportional relationship.

graph 5=10x

Step-by-step explanation:

thatle give you the line

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
