Answer:

The value of $x=-4$ . The figure is also attached below.

Step-by-step explanation:

Considering the expression

$5x + 6(x - 2) - 8 (x - 3)$

If we have to find the vale of $x$ , then

$5x + 6(x - 2) - 8 (x - 3)=0$

$5x+6x-12-8\left(x-3\right)=0$

$5x+6x-12-8x+24=0$

$3x+12=0$

$\mathrm{Subtract\:}12\mathrm{\:from\:both\:sides}$

$3x+12-12=0-12$

$3x=-12$

$\mathrm{Divide\:both\:sides\:by\:}3$

$\frac{3x}{3}=\frac{-12}{3}$

$x=-4$

Therefore, the value of $x=-4$ . The figure is also attached below.

For this case we have the following equation:
$d = \sqrt{\frac{3h}{2}}$
Where,
d: the distance they can see in thousands
h: their eye-level height in feet
For Kaylib:
$d = \sqrt{\frac{3(48)}{2}}$
$d=\sqrt{3(24)}$
$d=\sqrt{72}$
$d=6\sqrt{2}$
For Addison:
$d = \sqrt{\frac{3(85\frac{1}{3})}{2}}$
$d = \sqrt{\frac{256}{2}}$
$d=\sqrt{128}$
$d=8\sqrt{2}$
Subtracting both distances we have:
$8\sqrt{2} - 6\sqrt{2} = 2\sqrt{2}$
Answer:
$2\sqrt{2}$

Which of the following is NOT equivalent to 40/100?

frozen [14]

Answer:

Option C

Step-by-step explanation:

40/10 simplifies to 4.

40/100 simplifies to 0.40.

$\frac{40/10}{10/10} =\frac{4}{1} =4$

$\frac{40}{100} =0.40$

Therefore:

$\frac{40}{10}\neq \frac{40}{100}$

Option C should the the correct answer.
