Автор ответа: iramazurk

Пошаговое объяснение:

306 бутылок = 0,7 л

х бутылок = 0,3 л

х/306 = 0,7/0,3

0,3 * х = 0,7 * 306

0,3х = 214,2

х = 214 ,2 : 0,3

х = 714

1_________to the United States and got a job at a camp in northern Virginia. My teammate that
summer was Dan from Mississippi, and I am from Rhode Island. We worked together with a group

rangers came the next morning, we didn’t want to 7_________. "Can't we just tell a few more
stories?" In the cave, that night, I became a storyteller.
