The United States bought Alaska in 1867 to Russia.

Explanation:

The Alaska Purchase was a transaction in which the United States purchased Alaska, an area of about 1.5 million square kilometers, from Russia in 1867. The purchase price was $ 7.2 million.

Russia abandoned Alaska because it was expensive and difficult to control. In addition, Russia feared losing Alaska anyway to the United States. In the United States, the purchase of Alaska was supported, even though it was barely seen in the 19th century. It was not until the 20th century that Alaska became an important region for the United States, when its natural resources were used more efficiently and its strategic location became more prominent.

the perimeter of a triangle is 69 cm. side a is 5 cm shorter than side b. side c is twice as long as side a. find the length of each side. i need to know how to do it in 2 equations.  

equations:

a = b-5

c = 2a

a + b + c = 69
