A map of Squareville shows its 12 streets (line segments) and 8 intersections (A, B, C, ... , H) as shown. In how many different ways can someone travel from A to H along the streets without passing through any intersection more than once, or travelling along the same street more than once?

This is from Moems and the answer is 12??

Step-by-step explanation:

16

Step-by-step explanation:

where's the diagrams?

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
