Answer:

the value of the variable x is 16

Step-by-step explanation:

$given \: expression \\ \frac{5}{8}x = \frac{1}{2} x + 2 \\ substract \: \frac{1}{2} x from \: both \: sides \\ \frac{5}{8}x - \frac{1}{2} x = \frac{1}{2} x - \frac{1}{2} x + 2 - \frac{1}{2} x \\ factor \: out \: common \: x \\ x( \frac{5}{8} - \frac{1}{2} ) = \frac{1}{8} \\ simplify \\ \frac{1}{2} x + 2 - \frac{1}{2} x \: \frac{1}{2} x - \frac{1}{2} x = 0 = 2 \\ \frac{1}{8} x = 2 \\ multiply \: both \: sides \: by \: 8 \\ 8. \frac{1}{8} x = 2.8 \\ simplify \\ x = 16.$

ANSWER

$(4n - 1)\sqrt{3 n} + 3\sqrt{n}$

EXPLANATION

The given expression is

$\sqrt{48 {n}^{3} } + \sqrt{9n} - \sqrt{3n}$

We remove the perfect squares under the radical sign.

$\sqrt{16 {n}^{2} \times3 n} + \sqrt{9n} - \sqrt{3n}$

We can now take square root of the perfect squares and simplify them further.

$\sqrt{16 {n}^{2}} \times \sqrt{3 n} + \sqrt{9} \times \sqrt{n} - \sqrt{3n}$

This simplifies to:

$4n\sqrt{3 n} + 3\sqrt{n} - \sqrt{3n}$

This further simplifies to:

$(4n - 1)\sqrt{3 n} + 3\sqrt{n}$

A line passes through the points 3,10 and 6, 16 write the equation of this line in slope-intercept form

cluponka [151]

$(\stackrel{x_1}{3}~,~\stackrel{y_1}{10})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{16}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{16}-\stackrel{y1}{10}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{3}}} \implies \cfrac{ 6 }{ 3 } \implies 2$

$\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{10}=\stackrel{m}{ 2}(x-\stackrel{x_1}{3}) \\\\\\ y-10=2x-6\implies {\Large \begin{array}{llll} y=2x+4 \end{array}}$

What is the translation rule for this translation?

Anna35 [415]

Answer:

T(x,y)->(x-3,y-6)

Step-by-step explanation:

Say we take point E and E1. To move E to E1, we need to move it to the left 3 units, already giving us x-3. Then, we need to find out how far down it moved. by counting the units, we can tell that it moved 6 units down as well, giving us y-6. In the end, we get T(x,y)->(x-3,y-6).

You estimate that there are 44 marbles in a jar. The actual amount is 73 marbles. Find the percent error.

Svetlanka [38]

Answer:

Percentage Error in counting the marbles in the jar is 39.72%

Step-by-step explanation:

Estimated marbles in the jar = 44

Actual marbles in the jar = 73

⇒Error in Marbles = Number of actual Marbles - Estimated marbles

= 73 - 44 = 29

So, the error in counting marbles in the jar is 29.

Now, $\textrm{Percentage Error} = \frac{\textrm{Error in the Data}}{\textrm{Actual Data}} \times 100$

= $\frac{29}{73} \times 100 = 39.72$

or, Percentage Error = 39.72%

Hence, the Percentage Error in counting the marbles in the jar is 39.72%
