Answer 1

1
40/2=20
20-6=14
20+6=20

2

Answer 2

Пусть Х р стоит тюльпан,
Тогда (Х+12) - стоит роза
Х+(Х+12)=40
2х=40-12
2х=28
Х=14 р - стоит тюльпан
Х+12=14+12=26 р - стоит роза

1) 40-12=28 р - стоили бы тюльпан и роза при одинаковой цене
2) 28:2=14 р - стоит тюльпан
3) 14+12=26 р - стоит роза

Answer 3

Problem Analysis

We are given that the cost of a tulip is 12 rubles less than the cost of a rose, and the combined cost of a tulip and a rose is 40 rubles. We need to determine the individual costs of a tulip and a rose.

Solution

Let's assume the cost of a rose is x rubles. According to the given information, the cost of a tulip is 12 rubles less than the cost of a rose, so the cost of a tulip would be x - 12 rubles.

The combined cost of a tulip and a rose is 40 rubles, so we can set up the following equation:

x + (x - 12) = 40

Simplifying the equation:

2x - 12 = 40

Adding 12 to both sides:

2x = 52

Dividing both sides by 2:

x = 26

Therefore, the cost of a rose is 26 rubles.

Substituting this value back into the equation for the cost of a tulip:

x - 12 = 26 - 12 = 14

Therefore, the cost of a tulip is 14 rubles.

Answer

The cost of a rose is 26 rubles, and the cost of a tulip is 14 rubles.
