Answer:
Step-by-step explanation:
AD = CD { BD is median}
6x + 10 = 2x + 12
6x -2x = 12 - 10
4x = 2
x = 2/4
x = 1/2
AC= AD + CD
= 6x + 10 + 2x +10 {add the like terms}
= 8x + 20 { Now plugin the value of x}
![=8*\frac{1}{2}+22\\\\](https://tex.z-dn.net/?f=%3D8%2A%5Cfrac%7B1%7D%7B2%7D%2B22%5C%5C%5C%5C)
= 4 + 22
= 26
Answer:
The value of the car after 5 years is $ 13,035 to the nearest dollar.
Step-by-step explanation:
The formula for depreciation is
![V=P(1-r)^t](https://tex.z-dn.net/?f=V%3DP%281-r%29%5Et)
where
is the beginning price of the asset,
is the annual rate of depreciation written as a decimal,
![r=0.12](https://tex.z-dn.net/?f=r%3D0.12)
is the number of years, and V is the value after t years.
Now substitute all these values into the formula to get,
![V=24,700(1-0.12)^5](https://tex.z-dn.net/?f=V%3D24%2C700%281-0.12%29%5E5)
This simplifies to,
![V=24,700(0.88)^5](https://tex.z-dn.net/?f=V%3D24%2C700%280.88%29%5E5)
![\Rightarrow V=24,700(0.5277319168)](https://tex.z-dn.net/?f=%5CRightarrow%20V%3D24%2C700%280.5277319168%29)
![\Rightarrow V=13,034.97834](https://tex.z-dn.net/?f=%5CRightarrow%20V%3D13%2C034.97834)
The value of the car after 5 years is $ 13,035 to the nearest dollar.
Answer: the number is 9
Explanation:
4x - 9 = 27
Add 9 to both sides:
4x = 36
Divide both sides by 4:
x = 9
