Did you like the city? What is liked and what is not liked in the city, the people? What did you see interesting in new York? Where did you go tonight? What interesting places have you visited? What was the weather like? Did you address the question to passers-by and how did they react to it? Were people sociable and friendly with you? Did they help you in finding an unfamiliar place or passed by indifferently? Did you understand their English?
240/(х-18)=120
(х-18)/240=1/120
Тут якобы делиться 240 на 120
х-18=2
х=18+2
х=20
3м.=300см; 1дм.=10см значит 4дм.=40см; ну и 5см. 300+40+5=345см.
1) 3м.3дм.5см.
2) 3м.
3) 3м.2дм.4см.
4) 3м.15см.
или
1) 345-10=335см.
2) 345-45=300см.
3) 345-21=324см.
4) 345-30=315см
Х на коридор
х+3 на спальную
у на столовую
система:
3х=у
х+х+3+у=23
решаем:
х+х+3+3х=23
5х=20
х=4
4*3=12 рулонов для столовой
Ответ:
надо подобрать наибольший общий делитель НОД. Он равен 38.
1вагонов: 418 : 38= 11 2вагонов: 494 : 38 = 13
3вагонов 456 : 38 = 12
