Ответ: 1.х = 9500

2. с = 7.

Пошаговое объяснение:

1.Потрібно знайти значення змінної х. Спочатку перенесемо -60 * 100 на праву сторону рівняння, щоб отримати х в одиночному виді:

х - 60 * 100 = 3500

х = 3500 + 60 * 100

х = 3500 + 6000

х = 9500

2.Потрібно знайти значення змінної с. Спочатку виконаємо ділення на правій стороні рівняння:

630 : с = 140 - 50

630 = с * (140 - 50) (перенесемо с на ліву сторону, зведемо з правої сторони дужки)

630 = 90с

с = 630 / 90

с = 7

17. ________
When I was young, I don’t think there was ever any doubt in my mind about what job I intended to
do for the rest of my life. However, I agree that it probably seemed a rather strange ambition for a
child to want to be a politician rather than a footballer or astronaut. I’m quite sure that the person
who was responsible for this was my grandfather. When he became the local Mayor, I was very
impressed by the golden chains he wore!
18. ________
I inherited his love of debate and, apparently, even at primary school, I used to argue a lot with
the teacher about school rules and fairness in the classroom. I remember one school report when
she wrote that I had very strong views on a wide range of topics, and my parents got quite angry
with me for not doing what the teacher told me.
19. ________
By the time I was a teenager, my parents were getting very worried about me. They wanted me to
be a doctor, but I had no interest in this at all! In fact, the only thing I was interested in was
reading newspapers, which was very odd for a young teenager! Then, I joined the UK Youth
Parliament, and they realised that I was serious about becoming a politician.
20. ________
The UK Youth Parliament was very good training for me, and, some years after, I went on to be
elected as a Member of Parliament for my own area. In the beginning, my parents were unhappy
about my choice of career. They wanted me to choose a job which was well-paid with security,
and it didn’t help that my political beliefs were completely different from theirs! But I’ve been a
politician for four years, and they’re really happy now.
21. ________
It’s interesting how people react when I tell them that I’m an MP. Some think that I must be very
caring and want to change the world, whereas others think that all politicians are rich and never
tell the truth! I suppose politicians, in general, have a bad reputation, but I’m sure that young MPs,
like me, really do want what is best for the people and our country. I hope so, anyway.
