   (7,5x(-3.5)-2.5x3,5)x1,9:(-17,5)

= [7,5x(-3,5)+2,5 x(-3,5)] x1,9:(-17,5)

= [(7,5+2,5)x(-3,5)] x1,9:(-17,5)

=[10x(-3,5)]x1,9:(-17,5)

=(-35)x1,9:(17,5)

=(-66,5) :(17,5)

=3.8

1. _________________

Dortmund is one of the most important cities in the north-western part of Germany. It is close to Essen, Dusseldorf, Cologne and other major cities in the Ruhr and Rhineland area. It used to be a center of the coal mining and steel industries.

2. _________________

Dortmund is famous for its beer. There are five breweries. It also has a theater, a small opera house, a very large sports stadium and a well-known football team. The surrounding countryside is very attractive. In addition, a national garden exhibition takes place there each year.

3. _________________

Dortmund has a wide range of hotels and other accommodation for tourists. Rail connections are particularly good. It also has a small airport with flights to most major German cities.

4. _________________

Although Dortmund is not famous for its cuisine, there are many restaurants there that offer excellent value for money. Local pubs also serve excellent beer and light meals.

5. _________________

I would recommend a stay of one or two days in Dortmund to tourists who are interested in visiting a typical, middle-sized German city.
