i included how the second part of the question below

Answer 1

Museum is 5 blocks east and 7 blocks south from Ruby's hotel.

Explanation:

Let Ruby's hotel location be at point (0,0).

West = negative x-direction

East = positive x-direction

North = positive y-direction

South = negative y-direction

1. From her hotel she walks 2 blocks west and 3 blocks south to a coffee shop. Then her location is at point (-2,-3)

2. Then she walks 7 blocks east and 4 blocks south to a museum. Then her location is at point (-2+7,-3-4) that is (5,-7)

So, museum is 5 blocks east and 7 blocks south from Ruby's hotel.
