Afarmer planted 54 trees in 3 days. on the first day he planted 5 more trees than on the second day, and 2 less trees on the third day than on the second day. how many trees did he plant each day?

Answer:

The farmer planted 22 trees, 17 trees, 15 trees, on consecutive three days.

Step-by-step explanation:

Number of trees planted by Farmer = 54 trees in 3 days

On the first day he planted 5 more trees than on the second day,

And 2 less trees on the third day than on the second day.  

We have to find how many trees did he plant each day?

Let the number of trees planted on second day be n trees.

Now, number of trees planted on 1st day will be n + 5 tress

And, number of trees planted on 3rd day will be n – 2 tress.

Then, total trees planted = 54  

=>trees planted on 1st day + trees planted on 2nd day + trees planted on 3rd day = 54  

=>n+ 5 + n + n – 2 = 54  

=>n + n + n + 5 – 2 = 54  

=>3n + 3 = 54  

=>3n = 54 – 3  

=>3n = 51  

=>

=>n = 17  

So, number of trees planted on 2nd day are 17 tress.

Then, on 1st day = 17 + 5 = 22 trees and on 3rd day = 17 – 2 = 15 trees

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
