Answer:
I mean 6
Step-by-step explanation:
That is the answere to you question.
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.
Reverse your steps to see if u get what the questions originally asked.
Wherever you see an x, replace it with -2,
So f(-2) = 2(-2^2) -15
= (2x4)-15
= -7
24 / (3/8) =
24 * 8/3 =
192/3 =
64......there are 64 three-eights quart jars
