Ответ учителя по предмету Математика
Ответ: в первом 50 кг, во втором 10 кг.
Пошаговое объяснение:Пусть в первом ящике будет 5х мандарин, а во втором х мандарин. Потом в первом ящике стало (5х-25) кг. мандарин, а во втором (х+15). Известно, что после этого ящики были одинаковые. Имеем уравнение.
5х-25=х+15
5х-х=15+25
4х=40
х=10
В первом ящике было 10*5=50кг, а во втором 10кг
