Пошаговое объяснение:

9+2(2х+1)=1

9+2*2х+2*1=1

9+4х+2=1

4х+11=1

4х=-11+1

4х=-10

х=-10:4

х=-2,5

avangardnymph: Неверно . ты перепутала знак у числа 11 должен быть - стоять ( после переноса меняется знак на противоположный ) должно было быть -11 + 1

avangardnymph: Теперь все супер!

Peteys mother will be surprised becous...

c)the lady gave him a laste dinner
Текст
Well, Petey ran on and on. Bui he couldn't find a dog who would give his boy away. Petey was very sad. His little legs were very tired. My mother was right, he thought. There isn’t a boy to be found [невозможно найти мальчика). Just as it was getting dark, he came to a large building. Petey was walking by it slowly when he saw a sign: Home for Boys. “Maybe I could find a boy here!” said Petey to himself. “These boys have no parents, and no dog to take care of them." He walked slowly up to the home. He was so tired he could hardly lift his little paws (едва переставлял свои лапы). Then Petey stopped. He listened. He could hear music. He looked through the window. He saw a Christmas tree, and children singing carols (новогодние песни).Then Petey saw something else. In front of the building, all by himself (совершенно один), sat a boy! He was not a very big boy, and he looked lonely (одиноко), Petey gave a glad little cry. He forgot that he was tired. He jumped up and landed in the boy's lap (оказался па коленях у мальчика). Sniff, sniff, went Petey's little nose. Wag, wag, went Petcy’s tail. He licked the little boy with his warm, wet tongue. How glad the boy was to see Petey! He put both his arms around the little dog and hugged him (обнял его). Then the front door opened and a lady looked out. “Why, here you are, Ricky!” she said, “What are you doing here all alone (совсем один)? Come on in and sit near the Christmas tree.** Petey sat very still. The boy sat still* The boy looked up at the lady and down at Petey. Petey began to tremble (дрожать). Would the boy go in and leave him {бросит его)1 *Tm not alone,” said the boy, “I've got a puppy.” “A puppy!” The lady came out and looked at Petey in surprise (удивленно).Can he come, too?" said the boy. “Why,” said the lady, ‘"you’re a nice little dog. Where did you come from? Yes, bring him in/' “Come on, puppy,” cried the boy. A lot of boys were playing around the Christmas tree. They rushed (бросились к) to Petey. They were so happy to see him. Petey wagged (вшч) his tail. He wagged his fat little body. He licked {облизал) every one of the boys. “Can we keep him?" said one, “Can we give him some dinner?” said another.“Can we make him a nice warm bed?” said a third. “We will give him some dinner and a nice warm bed,” said the lady.tomorrow we will find his mother and see if she'll let him stay," Petey knew his mother would let him slay. She knew how much he wanted a boy. “She’ll be surprised.” said Petey to himself, with a happy little smile, “when I lell her I got fifty boys for Christmas!"
