Answer:
16$
Step-by-step explanation:
Take away 9 from 17 (17-9=8) and since he used half his allowance on a movie double 8 to get 16$
Answer:
Height of the building = 50.8 ft
Step-by-step explanation:
A person and a building are casting the shadows at the same time of the day.
Triangles formed by the person and his shadow and the building and its shadow will be similar.
Therefore, corresponding sides of the similar triangles will be proportional.

x = 
x = 50.75
x ≈ 50.8 ft
Answer:
Area = 9
Step-by-step explanation:
Remark
It's a right triangle. Therefore the area can be found with the two legs (a and b)
Givens
a = 3
b = 6
Area = a*b/2
Solution
Area = 3*6/2
Area = 18/2
Area = 9
Answer:
x = 
Step-by-step explanation:
Given
+
-
= 
Multiply through by wxyz to clear the fractions
2xyz + 3wyz - 4wxz = wxy ( subtract wxy from both sides )
2xyz + 3wyz - 4wxz - wxy = 0 ( subtract 3wyz from both sides )
2xyz - 4wxz - wxy = - 3wyz ( factor out x from each term on the left side )
x(2yz - 4wz - wy) = - 3wyz ( divide both sides by (2yz - 4wz - wy )
x =
( multiply numerator/ denominator by - 1 )
x =
