Пошаговое объяснение:

обозначим длину равных участков за х, тогда будем иметь такое уравнение:

$x + x + x + 235 = 520$

решая уравнение получим:

$3x + 235 = 520 \\ 3x = 520 - 235 \\ 3x = 285 \\ x = 95$

INDIVIDUAL AND SOCIETY

Every group of people must solve three basic problems of daily living: what goods and services to produce, how to produce these goods and services, and for whom to produce these goods and services.
Economics is the study of how society decides what, how, and for whom to produce. By goods we mean physical commodities such as steel, cars, and strawberries. By services we mean activities such as massages or live theatre performances which can be consumed or enjoyed only at the instant they are produced. In exceptional circumstances, society may find that some of the questions about what, how, and for whom to produce have already been answered; until the arrival of Man Friday, Robinson Crusoe need not worry about the 'for whom' question. In general, however, society must answer all three questions. By emphasizing the role of society, our definition places economics within the social sciences, the sciences that study and explain human behaviour. The subject matter of economics is that part of human behaviour which relates to the production, exchange, and use of goods and services. The central economic problem for society is how to reconcile the conflict between people's virtually limitless desires for goods and services, and the scarcity of resources (labour, machinery, and raw materials) with which these goods and services can be produced. In answering the questions what, how, and for whom to produce, econo¬mics explains how scarce resources are allocated between competing claims on their use. Because economics is about human behaviour, you may be surprised that we describe it as a science rather than a subject within the arts or humanities. This reflects the way economists analyse problems, not the subject matter of economics. Economists aim to develop theories of human behaviour and to test them against the facts.
