Step-by-step explanation:
The third table shows a relationship of y=2x.
_____
Essentially, you have to see whether the value of y/x is constant for all the values in a table. If it is not, then the relation is not proportional.
in the first table, -4/-2 ≠ -3/-1
in the second table, -4/-2 ≠ 3/1
in the fourth table, -4/-2 ≠ 6/2
For this case we have that each student takes 8 \ frac {3} {4} minutes to perform and play 3 songs. Then, we convert the mixed number to a fraction:
Thus, each student takes minutes.
If there are 9 students in the recital then we have:
minutes.
Thus, the recital lasts at least 78.75 minutes.
