Answer:
Step-by-step explanation:
Let s represent the length of each of the three sides mentioned. The length of the fourth side is 7 inches. Adding the lengths of the four sides together yields 10 inches: g + g + g + 7 = 10 (inches)
Then 3g + 7 = 10, or 3g = 3, or g = 1.
This equation is OK, but there's no solution, since 3g or just 3 is less than 7. With side lengths 1, 1, 1, 7, we cannot draw a quadrilateral.

Step-by-step explanation:
Given two expressions

and

Substitute y = 5 into each expression:
1.

2.

As you can see the results are the same.

let's plug in the value of y :
Answer:
a) Yes, i think it does represent a proportional relationship because the prices all go up by 12$.
b) The constant of proportionality is 12.
c) The equation would be 12(t) t= tickets idrk how else to put the equation feel free to correct me if im wrong.
D) the graph would look like : on the x axis would go up by 1,2,3,4,5,6 and so on, and on the y axis, count by 12's. (ex. 12,24,36,48)
E) The cost of 7 tickets would be 84$
Step-by-step explanation:
