Answer:
Step-by-step explanation:
Let the number of students be x
<u>Initial share was:</u>
<u>With the less students the share is:</u>
- 120 /(x - 8) = 120/x + 0.5
<u>Solve for x:</u>
- 120 /(x - 8) = 120/x + 0.5
- 120x = 120(x - 8) + 0.5x(x - 8)
- 120x = 120x - 960 + 0.5x² - 4x
- 0.5x² - 4x - 960 = 0
- x² - 8x - 1920 = 0
- x² - 8x + 16 = 1936
- (x - 8)² = 1936
- x - 8 = √1936
- x - 8 = 44
- x = 52
52 students
there is no numerical answer. however, if you were to combine them, the equation would be:
12q + y + 3/4, i’m pretty sure
