Пошаговое объяснение:

а = -2; в = 1,5

1) 3|а| - |в| = 3*|-2| - |1,5| = 3 * 2 - 1,5 = 6 - 1,5 = 4,5

Ответ: В

2) 2|а| + 1 = 2*|-2| + 1 = 2 * 2 + 1 = 4 + 1 = 5

Ответ: А

3) 4|а| - 1,5|в| = 4*|-2| - 1,5*|1,5| = 4 * 2 - 1,5 * 1,5 =

8 - 2,25 = 5,75

Ответ: Д

4) 2 1/2|а| + |в| = 2 1/2 * |-2| + |1,5| = 2 1/2 * 2 + 1,5 = 5/2 * 2 + 1,5 = 10/2 + 1,5 = 5 + 1,5 = 6,5

7 Read the article about a sea rescue. Seven sentences are missing from the article. Choose from the
sentences A-H the one which fits each gap. There is one extra sentence.
Long distance rescue
Most people have heard of the Titanic. It was the largest passenger ship in the world and was launched in 1912, but on its
very first voyage it hit an iceberg and sank in the Atlantic Ocean. Most of the 1,517 people on the ship died in the freezing
water. (1)
It is a very strange tale, but luckily it had a better ending than the story of the original Titanic.
Alex Evans works on a lifeboat in Wales and he spends a lot of his time rescuing people from the sea. They are usually
swimmers or fishermen who are stuck on rocks when the sea comes in. These rescues are usually simple and don't
require aeroplanes or international search-and-rescue operations. (2)
On Monday Alex was shopping with his mother when his mobile phone rang. He was surprised to get a signal and
answered it. He was even more surprised to hear the voice of his friend Mark Corbett, who was on a motorboat in the
Caribbean over 4,000 miles away. (3)
. He told Alex that the boat was sinking and they needed help! At
Then he heard the panic in Mark's voice and realised that it was a
. He was
first, Alex thought that it was a joke. (4)
real emergency. Mark said that there was a lot of water in the boat and they had lost power. (5)
using the satellite phone and the only number he could remember was Alex's!
Alex stayed calm and wrote down the information about where the boat was. (6)
and three hours later they found Mark's boat and rescued them. (7)
calling their boats Titanic in the future!
A Then he contacted an international rescue centre.
B Mark was with some other men, taking a boat to Grenada.
C However, he doesn't have a boat himself.
They sent out planes
Maybe boat owners should avoid
D Luckily everyone was OK because of the actions of a good friend 4,000 miles away!
E They couldn't use the long-range radio.
F This week he was part of a sea rescue that was a little different!
G Imagine someone phoning you and saying that they are on the Titanic and it's sinking!
H Now another boat with the same name has been in the news because it got into trouble at sea.
