On a map drawn to scale, 2 cm represents 870 km. How long would a line segment be that represents 130 km?

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

ur a slave imma whip you with my whip coon

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
