Думаю вы поймете уравнением , так что
х+х-30+3(х-30)=830
2х-30+3х-90=830
5х=830+120
5х=950
х=190
Ответ:В первый день продали 190 кг апельсинов

The greenhouse effect
Much is written about the tendency of the earth's temperature to rise and the "greenhouse effect" that would begin to alter the earth's climate by the end of the 1990s.
In faсt, the science of the phenomenon is more interesting than frightening. "The
greenhouse effect” results when CO2 and certain other gases in the atmosphere allow the
sun's ultraviolet rays to penetrate and warm the earth but then absorb the infrared energy
the earth radiates back into space – much as glass in a greenhouse effect does – forming a
kind of "thermal blanket" around the planet. Burning huge amounts of fossil fields, which
release CO2 into the atmosphere, man has raised the CO2 level from 280 to 340 parts per
million since 1860 And continued use of coal and other fossil fuels is expected to double
the concentration of the CO2 by the year 2050, elevating, the earth's temperature by 3 to 9
degrees Fahrenheit. The greenhouse effect will mean much more than hotter summers and
milder winters. It may alter rainfall, affect crop yields and eventually, as glaciers begin to
melt raise the level of the sea.
The temperature change is reported to be greater in the polar regions than near the
equator. In general, it is said that snowfall will begin later, the growing season will
lengthen and higher latitudes will get less rain.
If we can't prevent the greenhouse effect, we can prepare for it. Suggestions include
breeding plants that need lees water, improving irrigation systems and many others.
However, not all experts are convinced that the heat is coming. Some think that the use
of primary energy sources such as coal could decline 60 per cent by 2050 and, perhaps, if
the rate of fossil – fuel use is going down, the amount of CO2 is getting less every year.
