the scale on a map is 1 cm : 7km. if two cities are 15 cm apart of the map, what is the actual distance between the cities?

x = 105 km

Step-by-step explanation:

We can use ratios to solve

1 cm               15 cm

=

7 km            x km

Using cross products

1 * x = 7 * 15

x = 105 km

Step-by-step explanation:

Use cross multiply

so,

hope this helps

good luck! have a nice day!

step-by-step explanation:

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
