Ответ:

  1. 2 кг; А) 4х - х = 6
  2. В 1-м ящике 119 апельсинов, а во 2-м 17.

Пошаговое объяснение:

1. Арбуз весит в 4 раза больше, чем дыня. Сколько килограммов весит дыня, если она на 6 кг легче арбуз? Пусть дыня весит х килограммов. В каком случае уравнение составлено правильно?

А. 4х – х = 6

Б. х=4+x=6

B. х + 4 + x=6

Г. 4х+х= 6

А) 4х - х = 6

3х = 6

х = 6 : 3

х = 2 кг (дыня)

2. В одном ящике было в 7 раз больше апельсинов, чем во втором. Когда с первого ящика взяли 38 апельсинов, а со второго 14, то во втором ящике осталось на 78 апельсинов меньше, чем в первом. Сколько апельсинов было в каждом ящике сначала ?​

7х - 38 - 78 = х - 14

7х - 116 = х - 14

6х = 102

х = 102 : 6

х = 17

7х = 7 × 17

7х = 119

Noah's Ark

Noah was a very good man. He was not wealthy, but he was
honest and he worked hard. (1) He
believed in God and he prayed every day. He lived with his wife and
his children. One day, God spoke to Noah. He said, "Noah, I know that you
are a good man. (2) I am going to create a large storm.
I will destroy all of the bad things on the earth, but I will save
you and your family." Then God said,
"Build a large ark, Noah. Take your family on the ark with you. Also, take
two of every animal on the earth. Bring food and supplies for several months." (3) All of the people in the city
said that he was crazy, but Noah ignored them.
He believed what God said to him. Noah finished his ark. He
gathered his family and he gathered two of all of the animals on
the earth. (4) It rained and rained and rained. All of the people in
the city were frightened. They said, "Noah, help us! Let us
on your boat!" (5) It rained for forty days
and forty nights. It was the greatest flood ever. All of the people on the earth died in the flood. Noah and his
family floated on the water. (6) The rain stopped after forty days. (7)
"Noah wanted to see where land was. He
picked a bird from the ark. He said
to the bird, "I see only water around us. Fly away, bird! See if land is anywhere nearby!" But the bird
returned with no sign of land. Noah
continued this every day. (8) Noah saw the olive branch and understood that land was near. He said to his
wife, "Land is here! We are safe! God
saved us!"
