Answer:

x = 12/5

Step-by-step explanation:

Since the original is 10 and the second is 6, that means that the scale is 10:6 or 5:3. It can also be related as %60 of the length.

Step 1: Make an equation

10/6 = 4/x

Step 2: Cross Multiply

10x = 24

Step 3: Divide

10x / 10 = 24 / 10

24/10 = 12/5

x = 2.4
