Calculation of the Number of Seedlings Planted on Each Avenue

To calculate the number of seedlings planted on each avenue, we will use the information provided:

- 80 seedlings were planted in total across 3 avenues. - The number of seedlings planted on the second avenue is 20 more than the number planted on the first avenue. - The number of seedlings planted on the third avenue is 15 less than the number planted on the second avenue.

Let's break down the calculation step by step:

1. Let's assume the number of seedlings planted on the first avenue is x. 2. The number of seedlings planted on the second avenue is x + 20 (20 more than the first avenue). 3. The number of seedlings planted on the third avenue is (x + 20) - 15 (15 less than the second avenue).

Now, let's solve for x:

1. The total number of seedlings planted across all three avenues is 80: - x + (x + 20) + [(x + 20) - 15] = 80 - Simplifying the equation: 3x + 25 = 80 - Subtracting 25 from both sides: 3x = 55 - Dividing both sides by 3: x = 55/3

Therefore, the number of seedlings planted on each avenue is as follows:

- First avenue: 55/3 (approximately 18.33) seedlings - Second avenue: (55/3) + 20 (approximately 38.33) seedlings - Third avenue: [(55/3) + 20] - 15 (approximately 23.33) seedlings

Please note that the calculated values are approximate due to the division involved.

Answer:

The number of seedlings planted on each avenue is approximately as follows: - First avenue: 18.33 seedlings - Second avenue: 38.33 seedlings - Third avenue: 23.33 seedlings
