Would you be able to help me with this question I don't really understand

Okay, here we have this:

Considering the provided information, we are going to identify wich equation applies, so we obtain the following:

$x+19=2x$

Where x represents the uknown number. Then finally we obtain that the correct equation is the third one.

Now, let's find the missing number solving the equation:

$\begin{gathered} x+19=2x \\ 19=2x-x \\ 19=x \end{gathered}$

Finally we obtain that the number is equal to 19.

Novosadov [1.4K]

Complete question :

Vanessa and Zack are playing a game where the player with the lower score wins. At the end of the game, Vanessa has a score of -3 5/8 and Zack has a score of -3 2/3. Which statement explains who won?

Vanessa won. If you compare the decimal equivalents of their scores, -3.625 < -3.666.

Vanessa won. If you compare the decimal equivalents of their scores, -3.666 < -3.625.

Zack won. If you compare the decimal equivalents of their scores, -3.625 < -3.666.

Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625

Answer: Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625

Step-by-step explanation:

Given that :

Player with the lowest score wins ;

Vanessa's score = - 3 5/8

Zack's score = - 3 2/3

Converting to decimal:

Vanessa :

-3 5/8 = - 29 /8 = - 3.625

Zack:

-3 2/3 = - 11/3 = - 3.666

Comparing the scores :

From the negaryce side of a number line :

-3.666 comes before - 3.625, hence, - 3.666 is lower or lesser than - 3.625

-3.666 < - 3.625, hence Zack won

Find the slope of a line parallel to this given line

dybincka [34]

bearing in mind that parallel lines have the same exact slope, then any parallel line to the one above will have the same slope as that one.

$\bf \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \qquad \implies y = \stackrel{\stackrel{m}{\downarrow }}{-\cfrac{7}{3}}x-4$
