It’s most likely answer D
Given:
System of linear equations.
Explanation:
System 1:
![\begin{gathered} y\text{ = 3x + 15 } \\ y\text{ = 2x + 11} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20y%5Ctext%7B%20%3D%203x%20%2B%2015%20%7D%20%5C%5C%20y%5Ctext%7B%20%3D%202x%20%2B%2011%7D%20%5Cend%7Bgathered%7D)
The above system of equations can be simplified ELIMINATION BY SUBTRACTION.
System 2:
![\begin{gathered} 7x\text{ - 2y = 0} \\ y\text{ = 6x + 5} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%207x%5Ctext%7B%20-%202y%20%3D%200%7D%20%5C%5C%20y%5Ctext%7B%20%3D%206x%20%2B%205%7D%20%5Cend%7Bgathered%7D)
The above system of equations can be simplified using the SUBSTITUTION METHOD.
System 3:
![\begin{gathered} -3x\text{ - 5y = -5} \\ -3x\text{ + 5y = 5} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20-3x%5Ctext%7B%20-%205y%20%3D%20-5%7D%20%5C%5C%20-3x%5Ctext%7B%20%2B%205y%20%3D%205%7D%20%5Cend%7Bgathered%7D)
The above system of the equation can be simplified using ELIMINATION BY SUBTRACTION.
System 4:
![\begin{gathered} -5x\text{ - 4y = -6} \\ -7x\text{ - 4y = -2} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20-5x%5Ctext%7B%20-%204y%20%3D%20-6%7D%20%5C%5C%20-7x%5Ctext%7B%20-%204y%20%3D%20-2%7D%20%5Cend%7Bgathered%7D)
The above system of the equation can be simplified using ELIMINATION BY SUBTRACTION.
System 5:
![\begin{gathered} 5x\text{ + 2y = 0} \\ 15x\text{ + 7y = 0} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%205x%5Ctext%7B%20%2B%202y%20%3D%200%7D%20%5C%5C%2015x%5Ctext%7B%20%2B%207y%20%3D%200%7D%20%5Cend%7Bgathered%7D)
The above system of the equation can be simplified using ELIMINATION BY MULTIPLICATION.
Answer:
I think it is 12 but still not sure
Answer:
Step-by-step explanation:
1.609 km=1 mile
1 km=1/1.609 mile
![4.8 km=\frac{4.8}{1.609} ~miles=\frac{4.8*5280}{1.609} \approx~15,751.40~ft](https://tex.z-dn.net/?f=4.8%20km%3D%5Cfrac%7B4.8%7D%7B1.609%7D%20~miles%3D%5Cfrac%7B4.8%2A5280%7D%7B1.609%7D%20%5Capprox~15%2C751.40~ft)
