The value for x is x= -8y/3 +12
ANSWER

EXPLANATION
The area of a sector is calculated using the formula,

The arc measure is given as 45°
The radius of the circle is 8 inches.
We substitute to obtain,


Well the answer would be 14 because the stock fell for 2 days and it falls 7 points each day therefore the answer that is an integer is 14
Well, its increasing by 2262 so if we multiply that number by 2, it equals 4524.So the total would be 10,524. If I'm wrong, I'm sorry.

Ratio
------------------------------------------------------------------------------------
Width : Length
2 : 5
Let x be the scale factor
Width : Length
2x : 5x
------------------------------------------------------------------------------------
Form equation and solve x
------------------------------------------------------------------------------------
Perimeter = 2(Length + Width)
70 = 2(5x + 2x)
70 = 2(7x)
70 = 14x
14x = 70
x = 5
------------------------------------------------------------------------------------
Find Length and Width
------------------------------------------------------------------------------------
Length = 5x
Length = 5(5)
Length = 25
Width = 2x
Width = 2(5)
Width = 10
------------------------------------------------------------------------------------
Answer: Length = 25 cm, Width = 10 cm
