Why do I want to go to America. Let's say, because I really like this country. She is very big and beautiful. There are a lot of cities in it. I want to see New York, Los Angeles and Disneyland. I want to see Niagara Falls. See the statue of liberty. In America they make my favorite phones and Arles watches. I wonder what Hollywood is and how movies are made there. See the Florida cosmodrome and crocodiles. I want to lie on the beaches of Mayami. I want to take a paddle boat trip on the Mississippi River. Visit the White House. To see the president of a great country. !
37*1/7-14*(1/7)^2=1/7*(37-14*1/7)=1/7*(37-2)=1/7*35=35/7=5
№2
Правильный вариант ответа 3, т.к. исходя из числовой прямой р=-1, q=2
Следовательно,
1)3q=3*2=3
2) p+q=-1+2=1
3) p-q=-1-2=-3
4) -pq=-(-1)*2=2
№4
х + 2 - 3(х - 4) = 4(2 + х) + 24
х+2-3х+12=8+4х+24
х-3х-4х=8+24-2-12
-6х=18
х=18:(-6)
х=-3
№7
(3 - а)² - а (а + 8)=3^2-2*3a+a^2-a^2-8a=9-14а,
при а=0,5 получаем 9-14а=9-14*0,5=9-7=2
№16
1 месяц=800 км
100 км=7 л
1л=23,5 руб.
800:100*7=56 л израсходовал агент за месяц
56*23,5= 1316 руб потратил агент на бензин за месяц
ответ: 1316 рублей
P.s. Прости, но с №3 и №20 я тебе не не помню как правильно решать. Сам как-нибудь
