The mistake is on the 3rd-4th line Cam added the 2 to 10 instead of subtracting it, the real answer is x=1/2
Hello,
In this geometric sequence, the ratio is (1/3)/(1/2)=(1*2)/(3*1)=2/3
1/2*2/3=2/6=1/3
1/3*2/3=2/9
2/9*2/3=4/27
4/27*2/3=8/81
The solution set is ![x=-\frac{11}{2}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B11%7D%7B2%7D)
Step-by-step explanation:
The given expression is ![3(x-2)=5(x+1)](https://tex.z-dn.net/?f=3%28x-2%29%3D5%28x%2B1%29)
Multiplying the terms, we get,
![3x-6=5x+5](https://tex.z-dn.net/?f=3x-6%3D5x%2B5)
Subtracting 3x from both sides of the equation,
![-6=2x+5](https://tex.z-dn.net/?f=-6%3D2x%2B5)
Subtracting 5 from both sides of the equation,
![-11=2x](https://tex.z-dn.net/?f=-11%3D2x)
Dividing both sides by 2, we get,
![-\frac{11}{2} =x](https://tex.z-dn.net/?f=-%5Cfrac%7B11%7D%7B2%7D%20%3Dx)
Thus, the solution set is ![x=-\frac{11}{2}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B11%7D%7B2%7D)

Answer:
$12
Step-by-step explanation:
If you're taking off 25% of the regular cost, "taking off" means subtracting. So if we subtract 25% OF 16, the word "of" means to multiply here. So our expression then becomes:
16 - .25(16)
16 - 4 = 12
So the CD will sell for $12.
