Ответ:

Подставим в выражение с + 7 и с -4 значение с = 12:

с + 7 = 12 + 7 = 19;

с - 4 = 12 - 4 = 8.

Подставим значение с = 13:

с + 7 = 13 + 7 = 20;

с - 4 = 13 - 4 = 9.

Подставим значение с = 14:

с + 7 = 14 + 7 = 21;

с - 4 = 14 - 4 = 10.

Подставим значение с = 23:

с + 7 = 23 + 7 = 30;

с - 4 = 23 - 4 = 19.

The Driving Test It was a bright Monday morning and was I was going to have a driving test for the sixth time. The examiner Mr White had asked me to drive in heavy traffic around rush hour and felt I did a very good job of it. Mr White then instructed me to drive out of town, as I was feeling very confident; I thought to myself I can do this. Sure that I had passed, I began to enjoy my test, as I was not nervous anymore. The examiner was satisfied with my driving and with a smile and said, 'Just one more thing, Mr Lee let us suppose that a young child unexpectedly crosses the road in front of you. When I tap on the window, I want you to stop the car instantly." I continued driving the car and after a few minutes later, the Mr White tapped loudly. Though the sound was very clear, I do not know why it took me a long time to respond. I suddenly hit the brake pedal so hard we were both thrown forward. The examiner looked at me sadly. 'Mr Lee,' he said, in an unhappy voice, 'you have just killed that child!' Answer the following sentences in full sentences: 1. How did Mr Lee drive in heavy traffic during his sixth driving test? 2. Was Mr Lee feel confident? STUDENT DRIVER 3. What did the examiner tell Mr Lee to suppose? DRIVING TEST 4. What would Mr Lee have to do when the examiner tapped on the window? 5. Did he tap loudly or not? Did Mr Lee react quickly enough or not?​
