On a map, 1 in. represents 20 mi. Two cities are 31 in. apart on the map.
How far apart are the actual cities?
O 23ļmi
O 60gm
O zom
O 75 m

620 mi.

Step-by-step explanation:

If 1 inch represents 20 miles, we have a ratio of 1:20.

Since the cities are 31 inches apart on the map, multiply 31 by 20:

The cities are 620 miles apart.

answer: no

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
