On a map. 5 centimeters represents 2 kilometers. Which formula can you se to relate the distance d in kilometers to the distance in centimeters on the
map?

Step-by-step explanation:

Both of these questions involve proportions. You can set up an equation using equivalent fractions. You want to express to ratio of cm to km in Part A. Given the scale factor 5 cm = 2 km, then we can let c = the number of cm that represent an actual distance of 5 km. The following equation can be formed:

5/2 = c/5

Both of these fractions are a ratio of cm to km. To solve, we can cross-multiply.

2c = 25

c = 12.5 cm  

You can use a similar process for Part B.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
