because added the rectangle size and added the 60 with 16
Answer:
So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by
2.5/1 . Then, 20 x 2.5=50. So the answer is 50 km<-------------- Final answer

Step-by-step explanation:
Answer:
The values of 
and 
so that the two linear equations have infinite solutions are 
and 
, respectively.
Step-by-step explanation:
Two linear equations with two variables have infinite solution if and only if they are<em> linearly dependent</em>. That is, one linear equation is a multiple of the other one. Let be the following system of linear equations:
(1)
(2)
The following condition must be observed:
(3)
After some quick operations, we find the following information:
, 
, 
The values of and so that the two linear equations have infinite solutions are and , respectively.
