Answer:
X=36
Step-by-step explanation:
Let x be the unknown number
Three quarters of a number =3x/4
Three was added =3x/4 +3
Final
3x/4 + 3= 30
Multiply through with 4
3x+ 12=120
3x=120-12
3x=108
X=108/3
X=36
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:
I explained above.
The first one represents a proportional relationship
