Based on the Gauss-Jordan Elimination method, and the matrix given, the next step would be to b. divide R2 by 2 and R3 by 3.
<h3>What is the next step in the Gauss-Jordan Elimination method?</h3>
The first row has already gone as low as it can so rows two and three need to be worked on.
The best way to do this is to divide Row 2 by 2 and Row 3 by 3. This then leads to the augmented matrix becoming:
[1 0 0 I 5]
[0 1 0 I 4]
[0 0 1 I 3]
In conclusion, option B is correct.

Given:
There are given that the two paths and one path are 2 miles from the road.
Explanation:
Suppose the distance from the playground to the road is x.
To find the value x, we need to use the cos function;
So,
From the cos function in the given right angle triangle:
![cos50^{\circ}=\frac{x}{2}](https://tex.z-dn.net/?f=cos50%5E%7B%5Ccirc%7D%3D%5Cfrac%7Bx%7D%7B2%7D)
Then,
![\begin{gathered} cos50^{\operatorname{\circ}}=\frac{x}{2} \\ 0.64=\frac{x}{2} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20cos50%5E%7B%5Coperatorname%7B%5Ccirc%7D%7D%3D%5Cfrac%7Bx%7D%7B2%7D%20%5C%5C%200.64%3D%5Cfrac%7Bx%7D%7B2%7D%20%5Cend%7Bgathered%7D)
Then,
![\begin{gathered} 0.64=\frac{x}{2} \\ x=0.64\times2 \\ x=1.28 \\ x=1.3mi \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%200.64%3D%5Cfrac%7Bx%7D%7B2%7D%20%5C%5C%20x%3D0.64%5Ctimes2%20%5C%5C%20x%3D1.28%20%5C%5C%20x%3D1.3mi%20%5Cend%7Bgathered%7D)
Final answer:
Hence, the correct option C.
Answer:
1.
Step-by-step explanation:
1. 2x-4=10
2x=14
x=7
2. 3x+3=2x-1
3x-2x=-1-3
x=-4
3. 7x+x=24
8x=24
x=3(
4. 5+x=-18
x=-18-5
x=-23
5. -14=10-6x
6x=10+14
6x=24
x=4
6. 2x-2=x+12
2x-x=12+2
x=14
7. 3x-31=2
3x=2+31
3x=33
x=11
8. 5x-14=16
5x=16+14
5x=30
x=6
9. 2x+8=4(5-x)
2x+8=20-4x
2x+4x=20-8
6x=12
x=2
10. 2x-3=3(1+x)
2x-3=3+3x
2x-3x=3+3
-x=6
