6 buses with 32 students per bus.....6 x 32 = 192 students
each row seats 8 students...192/8 = 24 rows will be needed for all students
2x-2 must be zero or greater, since we cannot have a negative quantity under the radical sign (unless we allow for imaginary roots).
Solving 2x-2≥0, we get x-1≥0, or x≥1. x must be equal to or greater than 1.
16 - 16, so the answer to the 2nd problem is the fourth one: x=4.
N/3>1
n>1*3
n>3 or (3,+∞)
Solution: n>3 or (3, +∞)
