Answer:
5, 7, 9
Step-by-step explanation:
Using the information given we get:
![5x-7=2z](https://tex.z-dn.net/?f=5x-7%3D2z)
![x+2=y\\y+2=z\\x+4=z](https://tex.z-dn.net/?f=x%2B2%3Dy%5C%5Cy%2B2%3Dz%5C%5Cx%2B4%3Dz)
![5x-7=2(x+4)\\5x-7=2x+8\\](https://tex.z-dn.net/?f=5x-7%3D2%28x%2B4%29%5C%5C5x-7%3D2x%2B8%5C%5C)
<em>Add 7 to both sides</em>
![5x=2x+15](https://tex.z-dn.net/?f=5x%3D2x%2B15)
<em>Subtract 2x from both sides</em>
![3x=15](https://tex.z-dn.net/?f=3x%3D15)
<em>Divide both sides by 3</em>
![x=5](https://tex.z-dn.net/?f=x%3D5)
Using these equations:
![x+2=y\\y+2=z\\x+4=z](https://tex.z-dn.net/?f=x%2B2%3Dy%5C%5Cy%2B2%3Dz%5C%5Cx%2B4%3Dz)
and
![x=5](https://tex.z-dn.net/?f=x%3D5)
We get:
![x=5\\y=7\\z=9](https://tex.z-dn.net/?f=x%3D5%5C%5Cy%3D7%5C%5Cz%3D9)
Answer:
Step-by-step explanation:
x = time
y = elevation
At x = 0 , y = 0
It takes the submarine 2 hours to make descent of 2100 ft
=> x = 2 , y = - 2100
Slope = ( -2100 - 0)/(2 - 0) = -1050
y - 0 = -1050 ( x -0)
=> y = -1050x
1050x + y = 0
represent the relationship between the submarine's elevation and time.
So you are rounding 60.89.
I don't know which way you are aiming for to round, but here are some possible answers.
61.00
60.90
61.90
the answer is 0.000000007
The numbering system we commonly use is called the decimal numbering system because it uses <u> 10 </u> symbols to represent all possible numbers.
A way of writing numbers is known as a number system.
There are the following number systems:
- Decimal number system: "Deci" meaning 10, implies that the number system consists of 10 digits or symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
- Binary number system: "Bi" meaning 2, implies that the number system consists of 2digits or symbols, namely 0, and 1.
- Octal number system: "Oct" meaning 8, implies that the number system consists of 8 digits or symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, and 8.
- Hexa-Decimal number system: "Hexa-Deci" meaning 16, implies that the number system consists of 16 symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
Hence, we can say that the numbering system we commonly use is called the decimal numbering system because it uses <u> 10 </u> symbols to represent all possible numbers.
