Пошаговое объяснение:

(42,2x - 3) * 5= x+ 10

211x - 15 = x + 10

211x - x = 10 + 15

210x = 25

x = 25 : 210

x = 5/42

Complete this speech about drugs by putting in although, despite, however or while. In some cases there is more than one possibility

Ladies and gentlemen. Today I want to explain why I think drugs should be legalized. Many people think that all drugs are illegal. () However.. different countries. For example, (1)... the legal situation is different in coca leaves are legal in some parts of South America, they are banned in the USA and many other countries. But even in the USA and Europe, it is not true that all drugs are illegal. (2).. tobacco and alcohol are seriously addictive, they are a regular aspect of most social gatherings in our countries. Not everybody who smokes tobacco or drinks alcohol is an addict, of course. Many regular smokers would like to cut down or stop, (3)... and in fact many have tried several times. their many attempts, they continue smoking, precisely because nicoline is so addictive. Anyway, what are the disadvantages of the illegal drugs remaining illegal? In the first place, illegality means that there is no quality control to protect the consumer People think they are buying cocaine, for example, (5)... the substance is perhaps mixed with dust or even poisonous powders. Also drugs on the street are fairly expensive so (6).. consumers might not have a job, they need their drugs and this quickly leads to stealing and prostitution in order to pay for them. Second, the drug industry generates enormous quantities of money, enough money to corrupt many police officers and politicians. We like to think that our authorities control crime. The reality, (7)... some countries crime controls the authorities. Ladies and gentleman, (8). is that in you may not like drugs, as long as drugs are illegal, they are outside democratic control.
