A is just a variable to cover up any number you want. <span>a can be anything you want, such as the money in your bank account.
a+3
a=200
200+3</span>
Answer:
6
because when you subtract 6 from 6 you get 0
6 - 6 = 0
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.
