This is found by dividing 32 by 2.4
Answer:y = y = (32 - 6x)/(7 - x)
Step-by-step explanation:
1. Distribute -> 7y - 56 + 24 = xy - 6x
2. Add Like Terms -> 7y - 32 = xy - 6x
3. Collect Like Terms -> 7y - xy = 32 - 6x
4. Factor Out the "y" -> y(7 - x) = 32 - 6x
5. Divide Out the Left "x" -> y = (32 - 6x)/(7 - x)
Mean = (1+3+3+4+4+4+4+5+5+5) / 10 = 3.8
answer
mean = 3.8
U can use the cosine or sine rules depending on the question/triangle
