Answer:
First get a common denominator then you divide the numerator then you get your answer
Step-by-step explanation:
Answer: 18
Step-by-step explanation:
0.25 or 1/4 can be answered correctly
there's 72 questions
0.25*72=18
The answer you have is good. You don't need to change anything.
Part A:
We see that this pair of equations has 1 solution. On a graph, the solutions of 2 (or more) lines is where the lines intersect. In this case, since these lines intersect 1 time, they have 1 solution.
Part B:
As previously mentioned, the solutions of multiple lines is where the lines intersect. In this case, since they intersect at (4,4), that is the solution.
