2 answers:
Answer:
The distance between the two towns is 225 km.
Step-by-step explanation:
We are given the following information in the question:
The scale of map is:
This means that a distance of 1 cm on map marks a distance of 75 km in reality,
We have to find the distance between two towns.
Distance between two towns on the map = 3 cm
Distance between towns =
We could use the concept of ratio to solve this problem:
Hence, the distance between the two towns is 225 km.

Hi there! :)
4x + 5x + 12 = 6(x - 2)
Combine like terms and distribute the coefficient outside of the parenthesis:
9x + 12 = 6(x) + 6(-2)
9x + 12 = 6x - 12
Subtract 6x from both sides:
9x - 6x + 12 = 6x - 6x - 12
3x + 12 = -12
Subtract 12 from both sides:
3x + 12 - 12 = -12 - 12
3x = -24
Divide both sides by 3:
3x/3 = -24/3
x = -8.
