School uniforms can be different. someone who likes to loose, someone loves strict . but the classical school uniforms for me still remains white top black bottom . certainly convenient to walk to school in the free form and mood rises , but then everyone would go to school as the street, and generally will not discipline . in my opinion school uniform should be comfortable, but at the same time practical beautiful. not necessarily, that would be all the same as one walked . it is important that at least the tone of all forms was the same . indeed, often it happens that someone shape black , gray someone , and someone even blue . it would be good if there were a choice between sundresses and skirts that you could choose to wear a vest , or simply blouse. and be sure to that would have introduced a day when students can come in free form . one day a week . for example , on saturday, in a short day , or monday , that would be preserved the atmosphere of relaxation . general school uniform should first like the student that would go to school with mood.

Масса второго арбуза равна   6 кг.

Пошаговое объяснение:

Обозначим массу второго арбуза буквой   х .  

       Так как масса двух арбузов равна 14 кг, получаем:  

                                                     х + 8   =   14 .  

       Найдем такое значение   x , при котором это равенство будет верно.

       Нам надо найти слагаемое по сумме и второму слагаемому.    

                                       х   = 14 – 8 ;         х   =   6 .    

               О т в е т:   Масса второго арбуза равна   6 кг.
