Answer:4 runners finished the race
Step-by-step explanation:
There were 60 runners to start a race.
In the first half of the race, 2/3 of them dropped out. This means that the number of runners that dropped out would be
2/3 × 60 = 40 runners
The number of runners that is left out would be
60 - 40 = 20
In the second half of the race, 4/5 of the remaining runners dropped out. This means that the number of runners that dropped out would be
4/5 × 20 = 16 runners
Therefore the number of runners left and also finished the race would be
20 - 16 = 4
4 runners finished the race

Answer:
D
B
Step-by-step explanation:
1. x² - 5x = 14
x² -5x -14 = 0
x² +2x -7x -14 = 0
x(x + 2) -7(x + 2) = 0
x - 7 or x + 2 = 0
x = 7 or x = -2
2. y² + 6y + 9 = 49
y² + 6y +9 -49 = 0
y² +6y -40 = 0
y² +10y -4y -40 = 0
y(y + 10) -4(y + 10) = 0
y -4 or y + 10 = 0
y = 4 or y = -10
