A special day in my family. On weekdays, all of my family members are at work or school. We have special days on weekends. In the morning, we all get up at 9 o'clock and go to Breakfast. Mom makes us pancakes and dad makes us fried eggs. Then we engaged in cleaning of Grandpa working in the garden, and I'm helping him to water the plants. Grandma likes to decorate the garden with flowers, I plant flowers with her. Dad and mom clean the house, I clean my room. Then we all visit our loved ones together, and in the evening we play Board games. This is how one of my special days goes.
пусть расстояние от зареченска до азс х км, тогда расстояние от азс до ивантеевки 7х км. составим уравнение: х + 7х = 800
8х = 800
х = 100
от зареченска до азс 100 км пути. т.к. расход бензина на 100 км составляет 9 л, а бензина имеется 10 л, следовательно машина доедет до азс и еще 1 л бензина останется.
