From the given statement the unknown number is found to be - 1
The given statements can written in algebraic form as follows;
the unknown number = x
the number is multiplied by 6 = 6x
four less than twice the same number = 2x - 4
then, from the given statement the final equation equation becomes;
6x = 2x - 4
This unknown number can be solved by collecting similar terms together;
6x - 2x = -4
4x = -4
divide through by 4
![\frac{4x}{4} = \frac{-4}{4} \\\\x = -1](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B4%7D%20%3D%20%5Cfrac%7B-4%7D%7B4%7D%20%5C%5C%5C%5Cx%20%3D%20-1)
Thus, the unknown number is - 1

Answer:
cosθ = ![-\frac{72}{97}](https://tex.z-dn.net/?f=-%5Cfrac%7B72%7D%7B97%7D)
Step-by-step explanation:
tanθ = -(65/72)
If it is in the 2nd quadrant, this means that y is positive but x is negative
tanθ= opposite/adjacent or (y/x)
tanθ=![\frac{65}{-72}](https://tex.z-dn.net/?f=%5Cfrac%7B65%7D%7B-72%7D)
We know that the adjacent value = -72 and the opposite value = 65
The hypotenuse can be get by the following
![\sqrt{(65)^2+(-72)^2} = 97](https://tex.z-dn.net/?f=%5Csqrt%7B%2865%29%5E2%2B%28-72%29%5E2%7D%20%20%3D%2097)
cosθ is just adjacent/hypotenuse
Our adjacent value is -72
Our hypotenuse is 97, therefore
cosθ = ![-\frac{72}{97}](https://tex.z-dn.net/?f=-%5Cfrac%7B72%7D%7B97%7D)
B and D
They both are divided by a negative so they will equal a negative. The reason why C isn’t right is because there is 2 negatives which make a positive.
