If x varies inversely as y and y varies directly as z, what is the relationship between x and z? A. x \(\alpha\) z B. x \(\alpha\) \(\frac{1}{z}\) C. a \(\alpha\) z\(^2\) D. x \(\alpha\) \(\frac{1}{z^2}\)
Show Content
Detailed Solution\(x \propto \frac{1}{y}\), y \(\propto\) zx = \(\frac{k}{y}\) y = mz Since y = mz, x = \(\frac{k}{mz}\), where k and m are constants. Hence, x \(\propto\) \(\frac{1}{z}\) |

Evaluate \(\frac{3\frac{1}{4} \times 1\frac{3}{5}}{11\frac{1}{3} - 5 \frac{1}{3}}\) A. \(\frac{14}{15}\) B. \(\frac{13}{15}\) C. \(\frac{4}{5}\) D. \(\frac{11}{15}\)
Show Content
Detailed Solution\(\frac{3\frac{1}{4} \times 1\frac{3}{5}}{11\frac{1}{3} - 5 \frac{1}{3}}\) = \(\frac{\frac{26}{5}}{\frac{18}{3}}\) = \(\frac{26}{5} \div \frac{18}{3}\)= \(\frac{13}{15}\) |

If x = \(\frac{2}{3}\) and y = - 6, evaluate xy - \(\frac{y}{x}\) A. 0 B. 5 C. 8 D. 9
Show Content
Detailed Solutionx = \(\frac{2}{3}\) and y = - 6xy - \(\frac{y}{x}\) \(\frac{2}{3} - (6)^2 - (-6) \div \frac{2}{3}\) = -4 - (6) x \(\frac{3}{2}\) = -4 - (-6) x \(\frac{3}{2}\) = -4 - (-9) = -4 + 9 = 5 |

Solve the equation: \(\frac{1}{5x} + \frac{1}{x}\)= 3 A. \(\frac{1}{5}\) B. \(\frac{2}{5}\) C. \(\frac{3}{5}\) D. \(\frac{4}{5}\)
Show Content
Detailed Solution\(\frac{1}{5x} + \frac{1}{x}\)= 3\(\frac{1 + 5}{5x}\) = 3 6 = 15x x = \(\frac{6}{15}\) = \(\frac{2}{5}\) |

A sum of N18,100 was shared among 5 boys and 4 girls with each boy taking N20.00 more than each girl. Find a boy's share. A. N1,820.00 B. 2,000.00 C. N2,020.00 D. N2,040.00
Show Content
Detailed SolutionLet a girl's share = x + 204x + 5(x + 20) = 18,100 4x + 5x + 100 = 18,100 9x + 100 = 18,100 9x = 18,000 x = \(\frac{18,000}{9}\) x = 2,000 \(\therefore\) Each boy gets N(2,000 + 20) = N2,020. |
