Ответы

Автор ответа: Sajoko

405 - (9х + 70 ) : 4 = 383
405 - (9х+70) = 383 * 4
405 - 9х - 70 = 1532
-9х = 1532 - 405 + 70
-9х= 1197
х = 1197 : (- 9)
х = - 133

annataryntaeva: что за ответ такой

Sajoko: если вы правильно написали условие, то ответ правильный, но мне кажется вы напутли со знаками

annataryntaeva: извените...

Sajoko: Условие правильно вы написали в вопросе или нет?

My family.
DearAnn!
I have read your letter at "email friends" and would like to make friends with you! Let me introduce myself. My name is Hans. I live in Berlin. I am 20. I live with my parents. My mother is a doctor. When I feel bad, she is the first to help. I also love her apple pie, which she makes every Sunday. Cooking is her hobby. My father is a teacher. His hobby is working in a little garden in front of our house. As my future profession is agronomist, I help him look after the trees and flowers. My younger brother Nick is not fond of nature. He spends all his free time with his computer. We are both students. We study at the same university. We are all different, but when we gather together on Sundays, we can talk for hours. We discuss our family needs and plans for the future. I think we are a united and friendly family! I would like to know more about your family!
Yours, Hans.
