On a map, 1 inch equals 10 miles. Two cities are 6 inches apart on the map. What is the actual distance between the cities?
The actual distance between the cities is ___ miles.

The answer is 60 miles.

Step-by-step explanation:

Each inch is 10 miles and there are 6 inches. This means that the cities and 60 miles apart.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
