Answer:
92
Step-by-step explanation:
Let x represent the mean test scores of each female student.
The total scores of 15 female students would be 
.
We have been given that the 17 male students in the class had a mean score of 60.
The total scores of 17 male students would be 
.
We know that mean is equal to sum of data divided by total numbers in data set.
We are told that a class of 32 students has a mean test score of 75.
Therefore, the mean score for the 15 female students was 92.

It is 50. the angles on the side of ABC are the same as on ACD, where they are labelled. When you add the two angles on the other side together, the answer is 50 degrees.
Answer:
The main difference is that one has the equal sign before it while the other has it after.
You can decide which one to use based on each individual expression. If you are still simplifying, put it like this: ()=. If you are done simplifying and have your answer and are using a parenthesis, put it like this: =()
