Answer:
a) - 11x - 94y / 12 b) x -4 / 5- 3x c) 12x - 11 /10y
Step-by-step explanation:
a) 2x - 6y / 4 - 4y - x/ 12 - 4x - 20y /3
6x - 18y / 12 - 4y - x / 12 - 16x - 80y / 12
= 5x - 14y / 12 - 16x - 80y / 12
- 11x - 94y / 12
b) x /5 - 4/ 3x = x -4 / 5- 3x
c) 2x -3/ 5y - 5- 2x / 10y + x/y
4x - 6 /10y - 5-2x/ 10y + 10x / 10y
2x - 11 / 10 + 10x / 10y
= 12x - 11 /10y
Answer:405 meters apart. I think the m means meters, if it meant miles that would be incredible :)

Answer:
40 ft
Step-by-step explanation:
The post is 8/12 = 2/3 as tall as the shadow is long. We expect the same relationship holds for the tree.
tree height = (2/3)(shadow length) = (2/3)(60 ft) = 40 ft
The tree is 40 feet tall.
