The scale on a map reads 1/2 inch = 30 miles. If two cities on the map are 5 % inches apart, find the actual distance between the cities.

3 miles

Step-by-step explanation:

5% of one inch = 0.05 inches

0.5/30 = 0.05/x

0.5x = 1.5

x = 3

Notice how you can also simply divide 30 by 10 in this case? :)

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
