Intersecting chords are chords that intersect one another at a point
The value of n is -18
<h3>How to determine the value of n</h3>
Using the intersecting chord theorem, we have:
![\frac{7}{n + 4} = \frac{5}{n + 8}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7Bn%20%2B%204%7D%20%3D%20%5Cfrac%7B5%7D%7Bn%20%2B%208%7D)
Cross multiply
![7n + 56 = 5n + 20](https://tex.z-dn.net/?f=7n%20%2B%2056%20%3D%205n%20%2B%2020)
Collect like terms
![7n - 5n =20 - 56](https://tex.z-dn.net/?f=7n%20-%205n%20%3D20%20-%2056)
Evaluate the differences
![2n =-36](https://tex.z-dn.net/?f=2n%20%3D-36)
Divide through by 2
![n = -18](https://tex.z-dn.net/?f=n%20%3D%20-18)
Hence, the value of n is -18

Answer:
1
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
So the system is:
5x+13y=232
12x+7y=218
------------------
Let's look at the options to see which will work:
A) Multiply first equation by -13: -65x-169y=-3016
& second equation by 7 : 84x+49y=1526
There are no opposites in the either one of the variable columns so not this option.
B) Multiply first equation by 7: 35x+91y=1624
& second equation by 13 : 156x+91y=2834
There are no opposites in the either one of the variable columns so this is not option unless we were asked to subtract the equations.
C) Multiply first equation by -12: -60x-156y=-2784
& second equation by 5 : 60x+35y=1090
There is a column that contains opposites here so when you add the equations the x-variable will get eliminated.
Answer:
6x2−3x−20
Step-by-step explanation:
Let's simplify step-by-step.
x2+5x2−3x−20
=x2+5x2+−3x+−20
Combine Like Terms:
=x2+5x2+−3x+−20
=(x2+5x2)+(−3x)+(−20)
=6x2+−3x+−20
Well, if 74 cartons are orange juice out of 146 of them, we can make the fraction 74 over 146 (74/146) Now this fraction can also become smaller to get a more precise fraction. If we divide each part of the fraction by 2, we get (37/73). So, thirty seven cartons out of seventy three cartons are orange juice. Hope this helps! :)
