Answer:
Exact form: - 1/8
Decimal form: -0.125
Answer: 
Step-by-step explanation:
Add 
on both sides and subtract 
on both sides to leave x's on the left side and independent values on the right.
Solve the fractions.
Convert the mixed fraction 
to an improper fraction. You can do this by multiplying 1 times 35 and adding 2.
Now use the reciprocal (inverse fraction) and multiply on both sides to isolate x.
Answer:
10x2y3 -4xy2
Step-by-step explanation:
Just take the like terms and separate them-
1) 4x2y3 - (-7x2y3)= 10x2y3
2)2xy2 - 6xy2= -4xy
3)-2y - (-2y)= 0y
Hope this helps :)
It appears that the Pythagorean theorem can be applied to this problem
(distance to shadow)² = (height of building)² + (length of shadow)²
(38 m)² = (height of building)² + (28 m)²
660 m² = (height of building)²
Then the height of the building is
height of building = √660 m ≈ 25.7 m
6x + 5 = 4x + 5
2x + 5 = 5
2x = 0, x = 0
Y = 6(0) + 5, y = 5
Solution: x = 0, y = 5
