Answer:
26/52 50%
Step-by-step explanation:
52 cards in a deck, 26 are black and 26 are white.
We have:
3x + 4y = 12
The first thing we should do in this case is clear and.
We have then:
4y = -3x + 12
y = (- 3x + 12) / (4)
Rewriting:
y = (- 3/4) x + 3
We evaluate now for x = 4
y = (- 3/4) (4) + 3
y = -3 + 3
y = 0
The ordered pair is:
(x, y) = (4, 0)
Answer:
y = (- 3/4) x + 3
(x, y) = (4, 0)
Eight hundred seventy six thousand five hundred forty three.
Substitute 136.5 for y.
Compare this equation with
a = 1, b = - 191, c = 8190
or
or
or
or
or
or
x = 126 or x = 65
Hence, the points on the curve are (65, 136.5) and (126, 136.5).
The width of the air space is the distance between these points.
Width =
=
= 126 - 65
= 61
Hence, width of the air space is 61m.
