Answer 1

30+23+20=73(кг)-картофеля.
а легче
1)30+23=53
2)53+20=73(кг) - картофеля

Answer 2

Calculation of Vegetables Delivered to the School

To calculate the total weight of potatoes, carrots, and onions delivered to the school separately, we can use the information provided in the question.

According to the question, the weight of potatoes and carrots is 23 kg, and the weight of potatoes and onions is 20 kg. We need to find the weight of potatoes, carrots, and onions separately.

Let's assume the weight of potatoes is x kg, the weight of carrots is y kg, and the weight of onions is z kg.

From the given information, we can create the following equations:

1. x + y = 23 (equation 1) 2. x + z = 20 (equation 2)

To solve these equations, we can use the method of substitution or elimination.

Let's solve the equations using the method of elimination:

Subtracting equation 2 from equation 1, we get:

(x + y) - (x + z) = 23 - 20 y - z = 3 (equation 3)

Now, we have two equations: 1. y - z = 3 (equation 3) 2. x + z = 20 (equation 2)

Adding equation 3 and equation 2, we get:

(y - z) + (x + z) = 3 + 20 x + y = 23 (equation 1)

We can see that equation 1 is the same as the original equation 1. This means that equation 3 and equation 2 are independent and do not provide any additional information.

Therefore, we cannot determine the exact weights of potatoes, carrots, and onions separately based on the given information.

In conclusion, based on the information provided, we cannot determine the exact weights of potatoes, carrots, and onions separately.
