It took Laura 12.5 hours to read a 360 page book, how long would it take for her to read a 400 page book?

Lyrx [107]

$\bf \begin{array}{ccll} hours&pages\\ \cline{1-2} 12&360\\ x&400 \end{array}\implies \cfrac{12}{x}=\cfrac{360}{400}\implies \cfrac{12}{x}=\cfrac{9}{10} \\\\\\ 120=9x\implies \cfrac{120}{9}=x\implies \cfrac{40}{3}=x\implies 13.\overline{3}=x$

Angle APR is vertical with Angle SPL. If Angle APR = 13x - 30, and Angle SPL = 3x + 70, what is the value of x?

Luba_88 [7]

Answer:

The value of $x$ is 10.

Step-by-step explanation:

If APR and SPL are vertical angles, then we get that $\angle APR = \angle SPL$ . Given that $\angle APR = 13\cdot x -30$ and $\angle SPL = 3\cdot x + 70$ , we find that the value of $x$ is:

$13\cdot x - 30 = 3\cdot x +70$

$10\cdot x = 100$

$x = 10$

The value of $x$ is 10.
