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

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
