Q1: Solve the followir i) \( 4 \frac{1}{2}-\frac{x+5}{6}=\frac{4 x-1}{5} \)

Find the value of \( y \) in \[ \frac{1}{y}=27^{y} \]

3) \( x^{2}+5=13 \)

Directions: There are 30 questions in this section. Each question is followed by finathration alternatives. If \( \frac{a}{b}=\frac{3}{5} \) and \( \frac{b}{c}=\frac{20}{27} \) then \( \frac{c^{2}-a^{2}}{c^{2}+a^{2}} \) is (A) \( \frac{1}{7} \) (B) \( \frac{65}{97} \) (C) \( \frac{49}{81} \) (D) \( \frac{7}{25} \) (E) \( \frac{9}{19} \)

k) \( 2 x-y=8 \)

A) \( \frac{1}{5^{2}} \) B) \( \frac{1}{2^{3} \times 5} \) 3. In a class, "the number of boys \( (x) \) is 5 more than the number of girls \( (y) \)." The linear equation form of this statement is \( \begin{array}{llll}\text { A) } x-y=5 & \text { B) } x=5 y & \text { C) } y-x=5 & \text { D) } x+y=5\end{array} \)
