Answer:
15z - 9p
Step-by-step explanation:
7z - 9p + 9z - z
=7z - 9p +8z
= -9p + 15z or 15z - 9p Answer

<u>Answer:</u>
• Equation = ![2(\frac{7}{4}w + w) = 176](https://tex.z-dn.net/?f=2%28%5Cfrac%7B7%7D%7B4%7Dw%20%20%2B%20w%29%20%3D%20176)
• length = 56 ft
• width = 32 ft
<u>Step-by-step explanation:</u>
The ratio of the length to width is 7:4.
∴ ![\frac{l}{w} = \frac{7}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bl%7D%7Bw%7D%20%3D%20%5Cfrac%7B7%7D%7B4%7D)
⇒
[Equation 1]
We know that the perimeter of the garden is 176 feet.
∴ ![2(l + w) = 176](https://tex.z-dn.net/?f=2%28l%20%2B%20w%29%20%3D%20176)
⇒ ![2(\frac{7}{4}w + w) = 176](https://tex.z-dn.net/?f=2%28%5Cfrac%7B7%7D%7B4%7Dw%20%20%2B%20w%29%20%3D%20176)
⇒
[From Equation 1]
⇒ ![\frac{7 w + 4w}{4} = 88](https://tex.z-dn.net/?f=%5Cfrac%7B7%20w%20%2B%204w%7D%7B4%7D%20%20%3D%2088)
⇒ ![\frac{11w}{4} = 88](https://tex.z-dn.net/?f=%5Cfrac%7B11w%7D%7B4%7D%20%3D%2088)
⇒ ![11w = 352](https://tex.z-dn.net/?f=11w%20%3D%20352)
⇒ ![w = \bf 32 \space\ ft](https://tex.z-dn.net/?f=w%20%3D%20%5Cbf%2032%20%5Cspace%5C%20ft)
We know from Equation 1 that:
∴ ![l = \frac{7}{4} (32)](https://tex.z-dn.net/?f=l%20%3D%20%5Cfrac%7B7%7D%7B4%7D%20%2832%29)
⇒ ![l = \bf 56 \space\ ft](https://tex.z-dn.net/?f=l%20%3D%20%5Cbf%2056%20%5Cspace%5C%20ft)

Answer:
$13,793
Step-by-step explanation:
Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years. *
The formula for Depreciation rate =
y = a(1 - r) ^t
Where
y = Value of the car after t years
a = Initial value of the car = $23,000
t= time in years = 4 years
r = Depreciation rate = 12% = 0.12)
y = $23000 (1 - 0.12)⁴
y = $13792.99328
Approximately = $13,793:
