Answer: 12.5 or 12 1/2
Step-by-step explanation:
The given details are illustrations of addition and subtractions of fractions. The scuba driver is at an elevation of
ft below the sea level.
Given that:
--- the first dive
---- the additional dive
From the question, we understand that the diver starts at the sea level.
This is represented with 0ft.
So, the diver's elevation (d) is calculated as follows:
--- we use subtraction because the diver is below the sea level
So, we have:
![d = 0 - 1\frac 23 - 3\frac 25](https://tex.z-dn.net/?f=d%20%3D%200%20-%201%5Cfrac%2023%20-%203%5Cfrac%2025)
![d = - 1\frac 23 - 3\frac 25](https://tex.z-dn.net/?f=d%20%3D%20-%201%5Cfrac%2023%20-%203%5Cfrac%2025)
Convert fractions
![d = - \frac 53 - \frac{17}5](https://tex.z-dn.net/?f=d%20%3D%20-%20%5Cfrac%2053%20-%20%5Cfrac%7B17%7D5)
Take LCM
![d = \frac{-5 \times 5 - 17 \times 3}{15}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B-5%20%5Ctimes%205%20-%2017%20%5Ctimes%203%7D%7B15%7D)
![d = \frac{-76}{15}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B-76%7D%7B15%7D)
Reduce fraction
![d = -5\frac{1}{15}](https://tex.z-dn.net/?f=d%20%3D%20-5%5Cfrac%7B1%7D%7B15%7D)
The above value means that the diver's elevation is at
ft below the sea level.

Perimeter = 2(L + W)
2(L + 10) = 50
2L + 20 = 50
2L = 30, L = 15
Solution: the length is 15 inches
