Question

В саду адили 14 фруктовых деревьев груши сливы и яблони слив на 3 больше чем груш а яблонь меньше чем груш сколько деревьям посадили в саду решите задачу

Answer 1

X+(x+3) +(x-d) =14 ; x > d  если вообше  посадили яблони
3x=11+d ;
x=4 , если  d=1;
x=5 , если  d= 4 ;
x=6 ,если  d= 7   не решение 67
ответ:   {4 ;7; 3 } или  {5;8;1}.
 По другому : 
 Колич.яблонь:  y =14 - (x+x+3) =11 -2x;  где  и x натуральное число, причем :
0 <11-2x<x  ⇔2x<11<3x  ⇔11/3 < x <11/2  т.к . x  натуральное ,то⇒ 4 ≤  x ≤5 . 
Значит  x=4 или x= 5 .
ответ: { 4;7; 3   { 5 ; 8;1}.

Answer 2

Problem Analysis

We are given that there are 14 fruit trees in a garden, consisting of pear, plum, and apple trees. The number of plum trees is 3 more than the number of pear trees, and the number of apple trees is fewer than the number of pear trees. We need to determine how many trees of each type were planted in the garden.

Solution

Let's assume the number of pear trees is x. According to the problem, the number of plum trees is 3 more than the number of pear trees, so the number of plum trees is x + 3. The number of apple trees is fewer than the number of pear trees, so the number of apple trees is less than x.

To find the total number of trees, we can add the number of pear, plum, and apple trees together:

x + (x + 3) + (x - y) = 14

Simplifying the equation:

3x + 3 = 14

Subtracting 3 from both sides:

3x = 11

Dividing both sides by 3:

x = 11/3

Since we cannot have a fraction of a tree, we need to round the value of x to the nearest whole number. In this case, x would be 4.

Therefore, there are 4 pear trees, 4 + 3 = 7 plum trees, and 4 - y apple trees in the garden.

Answer

In the garden, there are 4 pear trees, 7 plum trees, and an unknown number of apple trees.
