The actual distance between two cities is 135 km. The map scale is 1cm: 100 km. Find the map distance.
defon

Answer:

1.35cm

Step-by-step explanation:

Given the scale of the map

1cm = 100km

For 135km;

x cm  = 135 km

Divide both equations

1/x = 100/135

100x = 135

x = 135/100

x = 1.35cm

Hence the map distance will be 1.35cm

How do i solve this kind of problem
Advocard [28]

Answer:

y=x-2

Step-by-step explanation:

to get -2 to -4 you would have to add -2

if we follow the pattern of subtracting 2 then you would see that -2 is b sense we are subtracting.

The m value doesn't have to change so we would leave the x how it is

The goal for this question is to find the pattern the numbers share though out the table.
