Given:
Consider the given expression is:
![10n-\dfrac{1}{3}(9n-12)](https://tex.z-dn.net/?f=10n-%5Cdfrac%7B1%7D%7B3%7D%289n-12%29)
To find:
The simplified form of the given expression.
Solution:
We have,
![10n-\dfrac{1}{3}(9n-12)](https://tex.z-dn.net/?f=10n-%5Cdfrac%7B1%7D%7B3%7D%289n-12%29)
Using distributive property, it can be written as:
![=10n-\dfrac{1}{3}(9n)-\dfrac{1}{3}(-12)](https://tex.z-dn.net/?f=%3D10n-%5Cdfrac%7B1%7D%7B3%7D%289n%29-%5Cdfrac%7B1%7D%7B3%7D%28-12%29)
![=10n-3n+4](https://tex.z-dn.net/?f=%3D10n-3n%2B4)
![=7n+4](https://tex.z-dn.net/?f=%3D7n%2B4)
Therefore, the correct option is A.
S is slope
S= rise/run
S1=3/12=1/4
S2=2/16=1/8
S3=5/15=1/3
S4=4/20=1/5
Deepest slope S3 aka C
Answer: The value of x is 155/79.
Step-by-step explanation:
13(6x -5 )-x= 13 -2(x +1)
78x - 65- x = 13 -2x -2
77x -65 = 11-2x
79x -65 =11
79x =76
x = 76/79 76/ 79 + 1/1 = 155/79
