4y + x = 4 . . . . . . . (1)
2y - x = 8 . . . . . . . (2)
(1) + (2) => 6y = 12
y = 12/6 = 2
From (2), 2(2) - x = 8
4 - x = 8
x = 4 - 8 = -4
Therefore solution is (-4, 2) and lies on both lines.
What do you need help with? What number? Or all of them?
The distance between two positions with longitudes A and B is given by ||A| - |B|| if the two positions are at the same side of the meridian (0 degrees longitude) and |A| + |B| if both positions are at different sides of the meridian.
Given that <span>Moscow is at 37.62 degrees longitude and Brasilia is at -47.87
degrees longitude, thus the two cities are at different sides of the meridian.
Therefore, the distance </span><span>(in degrees) between the longitude lines of Moscow and Brasilia</span> is |37.62| + |-47.87| = 37.62 + 47.87 = 85.49
Answer:
31 floors (32 floors if 0 counts as a floor)
