There are 6 Intersecting lines in a cube.
To convert the improper fraction
![\frac{1000}{859}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1000%7D%7B859%7D%20)
into a mixed number, you first want to
divide the numerator (1000)
by the denominator (859)
:
![1000 \div 859 = 1 R141](https://tex.z-dn.net/?f=1000%20%5Cdiv%20859%20%3D%201%20R141)
The
quotient, which is 1, will be your whole number part of your mixed number. The
remainder, 141, will become the numerator of the fraction part of your mixed number. The
original denominator of your improper fraction, 859, is still the denominator of your mixed number. So your mixed number form of your improper fraction is:
Your answer is ![1 \frac{141}{859}](https://tex.z-dn.net/?f=1%20%5Cfrac%7B141%7D%7B859%7D)
The good option to multiply the top equation by is <u>-4</u>
<h3>
REASON :-</h3>
This is because, when we solve the equations, in the left side of first equation :-
☆ -2 can be multiplied by <em>-4</em><em> </em>to get the value 8 on the left side of second equation.
☆ This can help in easier elimination in the given set of equations.
■ The process is to be done as per the given below way :
![(-4)×-2x - 5y = -1 \\ 8x + 4y = 16](https://tex.z-dn.net/?f=%20%28-4%29%C3%97-2x%20-%205y%20%3D%20-1%20%5C%5C%208x%20%2B%204y%20%3D%2016)
![= > ( - 4 \times - 2)x - 5y = -1 \\ 8x + 4y = 16](https://tex.z-dn.net/?f=%20%20%3D%20%20%3E%20%28%20-%204%20%5Ctimes%20%20-%202%29x%20-%205y%20%3D%20-1%20%5C%5C%208x%20%2B%204y%20%3D%2016)
![= > 8x - 5y = -1 \\ 8x + 4y = 16](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20%208x%20-%205y%20%3D%20-1%20%5C%5C%208x%20%2B%204y%20%3D%2016)
Now the 8x on both equations can be cut.

Answer:
A
Step-by-step explanation:
180-133= 47
180-142= 38
47+38= 85
180-85= 95
If the inside of n is 95, n has to be 85
