I divided the two fractions & drew a model.

So we know that the bird seed will last 2.5 days.
Knowing this, we can go with:
B. Rectangle model divided into six equal sections, five sections are labeled five-sixths and two sections are labeled one-third, equaling two and one-half days.
Let me know if you find any problems with my answer.
I'd say that the relationship between y and x is that they're both equivalent to each other, since -3 = -3.
Answer for #9 : 24,720
Answer for #10 : 145
Answer:
x = 34/21
Step-by-step explanation:
- 3 = 7/2 (3x-4)
- 3 = (21/2)x - 28/2
- 3 = (21/2)x - 14
- (21/2)x = 17
- 21x = 34
- x = 34/21
