Let the number be x.
(2/3)x = 3 1/2 + (3/8)x
(2/3)x - (3/8)x = 3 1/2
(8*2 - 3*3)/(8*3) x = 7/2
(16 - 9)/24 x = 7/2
(7/24)x = 7/2
7x/24 = 7/2 Divide both sides by 7
x/24 = 1/2
x = 24*1/2
x = 12
The number is 12.
Given :The scented burns inches in 20 minutes
The scented candle will burn inches in one hour.
The unscented candle burns inches in 30 minutes

Answer:
x²-16
Step-by-step explanation:
x²-16 =0
Add 16 to both sides
x²-16 + 16 = 0 + 16
Simplify
x²= 16
For x²=(fa) the solutions are x = √(fa), -√(fa)
X=√16 ,X= -√16
√16=4
-√16 = -4
x=4, x= -4
