Answer 1

To determine which expressions represent the time Whitney spends listening to her podcast over a five-day period, we need to calculate the total time spent listening. Given that Whitney listens to her podcast for 79 minutes each day, over a five-day period, the total time would be:

\[ 5 \times 79 \text{ minutes} \]

Now, let's evaluate the given expressions:

1. **79 + 79 + 79 + 79 + 79**: This expression adds up to the total time over five days, which is correct.
2. **7 ninths plus 7 ninths plus 7 ninths plus 7 ninths plus 7 ninths**: This does not represent the correct time and doesn't make sense in this context, as it doesn't relate to the minutes or hours involved.
3. **359**: This value alone does not work, as it doesn’t indicate how it relates to the total listening time.
4. **35 ninths**: This also doesn't fit the context or calculations, as it doesn't represent time.
5. **5 + 79**: This doesn't correctly represent total time either, as it simply adds 5 to 79.
6. **5×79**: This expression correctly represents the multiplication to find the total time spent over five days (5 days × 79 minutes).

Thus, the correct answers among the provided options are:

- **79 + 79 + 79 + 79 + 79** (This accurately calculates the total time in minutes)
- **5×79** (This accurately represents the time in a multiplication form)

The correct expressions are:
- 79 + 79 + 79 + 79 + 79
- 5 × 79
