Answer:
It has to be A because its the only one that makes sense
Step-by-step explanation:
6x^2-5x-1>0
(6x-1)(x+1)
x=1/6 x=-1
A) Who would not love birdies??
9 - 2(x + 6) =
9 - 2x - 12 =
-2x - 3 <=
Let the number of bike be x and the number of skates be y, then
21x + 20y ≥ 362 . . . (1)
2y = x . . . (2)
Putting (2) into (1), then
21(2y) + 20y ≥ 362
42y + 20y ≥ 362
62y ≥ 362
y ≥ 5.84
The least number of pairs of skates they need to rent each day to make their minimum is 6.
