Answer:
Step-by-step explanation:
In general, a solution of a system in two variables is an ordered pair that makes BOTH equations true. In other words, it is where the two graphs intersect, what they have in common. So if an ordered pair is a solution to one equation, but not the other, then it is NOT a solution to the system.
GCF (greatest common factor) is 1
Answer:
18 Tala.
Step-by-step explanation:
1. You have that Ming learned that the exchange rate is 6 Tala for $2. Therefore, if she exchanged $6, she would get:
2. Now, you must solve for , which is sthe amount of Tala:
3. Therefore, she would get 18 Tala.
Answer:
Because one letter represents an endpoint and the other doesn't.
