Answer:
2x5y7
Step-by-step explanation:
I believe the answer is the fourth option....because 13 × 3 is 39 5 × 3 is 15 and 12 × 3 is 36
I think this is.. ↓
grows 4% at every year
after 7 years ↓↓
4 × 7 = 28
A town has a population of 5000
28% of 5000 = 1400
5000 + 1400 = 6400
after 7 years, town has 6400 population = after 7 year grows 28%
See the attached picture.
The ratios are equivalent because you multiplied 18:4 by 2&3. And also you divided it by 2. I had the same homework!
