Solution
If cos x = - \(\frac{5}{13}\) where 180° < X < 270°, what is the value of tan x -sin x ?
A
\(\frac{111}{13}\)
B
\(\frac{321}{65}\)
C
\(\frac{216}{65}\)
D
\(\frac{112}{13}\)
E
\(\frac{131}{65}\)
medium Difficulty
Verified Correct Answer: Option C
Step-by-Step Mathematical Solution
Given \(\cos x = -\frac{5}{13}\) where \(180^\circ < x < 270^\circ\):
Using: \(\sin^2 x + \cos^2 x = 1\)
\(\sin^2 x = 1 - \left(-\frac{5}{13}\right)^2 = \frac{144}{169} \implies \sin x = -\frac{12}{13}\)
\(\tan x = \frac{\sin x}{\cos x} = \frac{-\frac{12}{13}}{-\frac{5}{13}} = \frac{12}{5}\)
Calculating \(\tan x - \sin x\):
\(\tan x - \sin x = \frac{12}{5} - \left(-\frac{12}{13}\right) = \frac{12}{5} + \frac{12}{13}\)
Finding a common denominator (65):
\(\tan x - \sin x = \frac{12 \times 13}{65} + \frac{12 \times 5}{65} = \frac{156}{65} + \frac{60}{65} = \frac{216}{65}\)
Thus, the value is:
\(\tan x - \sin x = \frac{216}{65}\)

Verified Correct Answer: Option C
Step-by-Step Mathematical Solution
(\(\frac{1}{343}\))\(^{\frac{1}{3}}\) + (64)\(^{-\frac{1}{3}}\) - \(\frac{4}{9}\)\(^{-\frac{1}{2}}\)
where \(343 = 7^3, 64 = 2^6, 4 = 2^2, 9 = 3^2\)
\(7^{-3}\) \(^{\frac{1}{3}}\) + \(2^6\) \(^{\frac{-1}{3}}\) - \(\frac{2^2}{3^2}\) \(^{\frac{-1}{2}}\)
\(7^{-1} + 2^{-2} - (\frac{2}{3})^{-1}\)
\(\frac{1}{7} + \frac{1}{4} - \frac{3}{2}\)
\(\frac{4+7-42}{28}\)

Solution
Given that \(\frac{(3 - y)}{2x}\) = \(\frac{(6y + 7)}{(4x - 5)}\), find the value of x when y = 2
A
\(\frac{64}{5}\)
B
6
C
\(\frac{5}{34}\)
D
\(\frac{-5}{34}\)
E
\(\frac{-64}{5}\)
medium Difficulty
Verified Correct Answer: Option D
Step-by-Step Mathematical Solution
Given:
\(\frac{3 - y}{2x} = \frac{6y + 7}{4x - 5}\)
Substitute y = 2
\(\frac{3 - 2}{2x} = \frac{6(2) + 7}{4x - 5} \implies \frac{1}{2x} = \frac{19}{4x - 5}\)
Cross-multiply: 1 \(\cdot\) (4x - 5) = 19 \(\cdot\) 2x
4x - 5 = 38x
-5 = 38x - 4x
-5 = 34x
x = -\(\frac{5}{34}\)
