Keep on dividing by 2
Answer:
x=-1
Step-by-step explanation:
0.5 ( 5 - 7x ) = 8 - ( 4x + 6 )
<u>- Distribute 0.5 by 5 and -7x</u>
2.5 - 3.5x = 8 - ( 4x + 6 )
Second- Distribute the invisible one into 4x and 6
2.5 - 3.5x = 8 - 4x - 6
- Combine like terms: Subtract 6 from 8
2.5-3.5x= - 4x + 2
-Add 4x from both sides of the equation
2.5 + 0.5x = 2
-Subtract 2.5 from both sides of the equation
0.5x = 2- 2.5
0.5x = -0.5
-Then divide each side by 0.5x
<u>0.5x</u> = <u>-0.5</u>
0.5 0.5
-Cancel the common factor of 0.5
x = <u>- 0.5</u>
0.5
-Divide -0.5 by 0.5
X = -1
Given:
The expression is
To find:
The value of given expression.
Solution:
We have,
![[\because \cos^{-1}(-\theta)=\pi -\cos^{-1}\theta]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Ccos%5E%7B-1%7D%28-%5Ctheta%29%3D%5Cpi%20-%5Ccos%5E%7B-1%7D%5Ctheta%5D)
![[\because \cos \dfrac{\pi}{3}=\dfrac{1}{2}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Ccos%20%5Cdfrac%7B%5Cpi%7D%7B3%7D%3D%5Cdfrac%7B1%7D%7B2%7D%5D)
![[\because \tan(\pi-\theta)=-\tan \theta]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Ctan%28%5Cpi-%5Ctheta%29%3D-%5Ctan%20%5Ctheta%5D)
![[\because \tan \dfrac{\pi}{3}=\sqrt{3}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Ctan%20%5Cdfrac%7B%5Cpi%7D%7B3%7D%3D%5Csqrt%7B3%7D%5D)
Therefore, the value of given expression is 
.
25 is A
26 is B because (8x2)+(11x3)=49
