140*3=420(у 1 кварт. буд.)
140*5=700(у 2 кварт.буд)

Answer 2

Calculation of the Number of Apartments in the First and Second Quarters

To determine the number of apartments built in the first and second quarters, we need to analyze the information provided.

According to the information given, in the first quarter, three identical buildings were constructed, while in the second quarter, five identical buildings were constructed. The total number of apartments in these buildings is 1120.

Let's denote the number of apartments in each building in the first quarter as 'x' and the number of apartments in each building in the second quarter as 'y'.

Based on this information, we can set up the following equations:

Equation 1: 3x = Total number of apartments in the first quarter Equation 2: 5y = Total number of apartments in the second quarter

We are given that the total number of apartments in both quarters is 1120. Therefore, we can write another equation:

Equation 3: 3x + 5y = 1120

To solve these equations, we need to find the values of 'x' and 'y'.

Let's proceed with solving the equations.
