The equations that represent the total number of tubes of paint the teacher bought are:
-
6×17=102
- This equation correctly calculates the total number of tubes by multiplying the number of packs by the number of tubes in each pack.
-
17+17+17+17+17+17=102
- This equation also accurately calculates the total by adding the number of tubes in each of the 6 packs.
The other options do not represent the total number of tubes bought:
- 17+6=23 is incorrect for this context.
- 23−6=17 does not pertain to calculating the total tubes either.
Thus, the correct responses are: 6×17=102 and 17+17+17+17+17+17=102.
