A=((a=b)/2)h
33=((4+7)/2)h
33=(11/2)h
33=5.5h

Answer:
Hence, the system of equations that is used to represent the situation is:
23x+7y=94-----(1)
16x+14y=38------(2)
Step-by-step explanation:
Let x represent the amount of points received for a correct answer and y represent the amount of points for an incorrect answer.
- You’ve gotten 23 questions correct and only 7 wrong,giving you a total score of 94 points.
So, the equation formed is:
23x+7y=94
- Your friend, on the other hand, got 16 questions correct and 14 wrong for a total score of 38 points.
So, the equation formed is:
16x+14y=38
Hence, the system of equations that is used to represent the situation is:
23x+7y=94-----(1)
16x+14y=38------(2)
