Solve for \( x \) in each: \( \begin{array}{l}1.1 \\ (x-1)^{2}=\sqrt{16} \\ 1.2 \quad 3 x^{2}-5 x=14 \text { (correct to two decimal places) } \\ 1.3 \quad x-2=\sqrt{8-x} \\ 1.4 \quad x^{2}+5 x<-6 \\ 1.5 \quad(\sqrt{81})^{x+1}=81^{2 x} \\ 1.6 \quad \text { If } \frac{3}{2} \text { is one root of the equation } b x^{2}-x=3 \text {, determine } b \text { and the other root. }\end{array} \) (3) (4)

3. At a school, \( 40 \% \) of the sikthegrade students said that hip-hop is their favorite kind of music. If 100 sixth-gade students preler hip hop music, how many sixth-grade studer are at the school? Explain or show your reasoning.

Find \( x \). \( \frac{x-1}{3}=\frac{5}{x}+1 \) A. 6.36 OR -2.36 (B) 6.36 (C) 5.46 OR 2.36 (D) No real roots

f) \( (-15 a b c+12 a b-9 a c-3 a) \div(-3 a) \)

expunencial \( \left.\left(4^{2}\right)\left(2^{3}\right)^{2 x-5}\right)=8 \)
