Question

Яблоко и груша вместе весят 140 г, груша и апельсин – 180 г, апельсин и яблоко – 160 г. Сколько граммов весят яблоко, груша и апельсин вместе взятые?

Answer 1

Я + г = 140
г + а = 180
а + я = 160
сложим эти равенства и увидим, что яблок - 2, груша - 2, апельсин - 2
2(а + г+ я) = 480
а + г+ я = 240
Ответ: 240 г.

Answer 2

Calculation of the Weight of Apples, Pears, and Oranges

To find the weight of the apple, pear, and orange combined, we can use a system of equations based on the given information.

Let's assign variables to the weights of the apple, pear, and orange: - Let A represent the weight of the apple. - Let P represent the weight of the pear. - Let O represent the weight of the orange.

From the given information, we have the following equations: 1. Apple + Pear = 140g 2. Pear + Orange = 180g 3. Orange + Apple = 160g

To solve this system of equations, we can use substitution or elimination. Let's use the substitution method.

From equation 1, we can express the weight of the apple in terms of the weight of the pear: - Apple = 140g - Pear

Substituting this expression for Apple in equations 2 and 3, we get: - (140g - Pear) + Pear = 160g - Pear + Orange = 180g

Simplifying these equations, we have: - 140g + Orange = 160g - Pear + Orange = 180g

From equation 4, we can express the weight of the orange in terms of the weight of the pear: - Orange = 160g - 140g = 20g

Substituting this expression for Orange in equation 5, we get: - Pear + 20g = 180g

Simplifying this equation, we have: - Pear = 180g - 20g = 160g

Now that we know the weight of the pear, we can substitute it back into equation 1 to find the weight of the apple: - Apple = 140g - 160g = -20g

However, a negative weight is not possible, so there seems to be an error in the given information or calculations.

Please double-check the given weights or provide additional information to resolve the discrepancy.

Note: The weights of the apple, pear, and orange combined cannot be determined with the given information.
