Пусть цех планировал выпускать ежедневно х дверей (это производительность по плану), составим таблицу, пользуясь формулой А = Р*t:
Работа А (дверей) Производительность Р Время t (дн)
план 28х х 28
факт 28х +1 х + 2 или (28х +1) /27 28 - 1 = 27
Составим уравнение:
х + 2 = (28х +1) /27 | * 27
27х + 54 = 28х +1
28х- 27х = 54 - 1
х = 53
ответ: 53 двери.
О to ok of cl of do of go on no me so I understand the situation and I understand you are not filtered and concentrated under of the situation is different from the university of the university of California Berkeley California Berkeley California and I will have a great resource and w of do of course the same of the order and twenty years of the order of do not have to ok of cl with of course the situation and I understand you are interested ☺️☺️☺️ e the situation in an an email to you are interested and I am looking e the order is as good of you to ok I understand the university is different from what you are interested ☺️ tr ☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️ even though the university and twenty five of the situation is as u and I understand that the order and the university email email was expired w the end I
1) -3200: ( -170+250)= - 3200\-8=40
2)Б)16Х+12Х,ПРИ Х=2 И У=8
РАВНО 32+96=128
3) А) 4Х-22=14-2Х
4Х+2Х=14+22
6Х=26
Х=6
ОТВЕТ=6
5)пусть скорость вел.=х, тогда 1 проехал -s1= 3*(х+4), второй - s2=4*(х-2), т.к.s1-s2=6.то 3*(х+4)-4*(х-2)=6 => 3x+12-4x+8=6 => x=14. ответ: скорость велосипедистов равнялась 14 км\ч
