Calcular el extremo desconocido, utilizando la definición de proporción: \( \begin{array}{ll}\frac{x}{8}=\frac{-5}{2} & \text { c) } \frac{-2 / 3}{1 / 4}=\frac{d}{1,2} \\ \frac{-10}{h}=\frac{-7}{14 / 5} & \text { d) } \frac{-5}{3,75}=\frac{-3 / 2}{n} \\ \text { Inir las razones que determinen una proporción: } & \end{array} \)

Find dif \( a_{1}=-17 \) and \( a_{13}=-29 \)

5. Bestäm värdet på \( a \) så att olikheten \( 2 x-a<5 \) har lösningen \( x<7 \)

\( \frac { 3 ) } { 3 x + 4 } = \frac { 2 x - 8 } { 3 } \)

Find the solutions. \( \left\{\begin{array}{l}x^{2}-4 y=29 \\ x^{2}+2 y=23\end{array}\right. \) > Next Question

Question 2 of 25 After the drama club sold 100 tickets to a show, it had \( \$ 300 \) in profit. After the next show, it had sold a total of 200 tickets and had a total of \( \$ 700 \) profit. Which equation models the total profit, \( y \), based on the number of tickets sold, \( x \) ?
