1) Factor using slide and divide: 

Explanation

The given answer is correct because when we multiply (2x - 1) and (x + 7) using the distributive property, we get 2x^2 + 14x - x - 7, which simplifies to 2x^2 + 13x - 7. This matches the expression given in the question, so (2x - 1)(x + 7) is the correct factorization.

6) Exchange Rates  Robyn spent two months traveling in New Zealand.  The day she arrived the exchange rate was 1.3 New Zealand dollars per every 1 U.S. dollar.  If she exchanged $500 U.S. dollars when she arrived, how much in New Zealand dollars did she receive?

Explanation

Robyn exchanged $500 U.S. dollars when she arrived in New Zealand. The exchange rate was 1.3 New Zealand dollars per every 1 U.S. dollar. To find out how much in New Zealand dollars she received, we need to multiply the amount of U.S. dollars by the exchange rate. Therefore, $500 multiplied by 1.3 equals $650. So, Robyn received $650 in New Zealand dollars.
