Answer:

164.32 earth year

Step-by-step explanation:

distance of Neptune, Rn = 4.5 x 10^9 km

distance of earth, Re = 1.5 x 10^8 km

time period of earth, Te = 1 year

let the time period of Neptune is Tn.

According to the Kepler's third law

T² ∝ R³

$\left ( \frac{T_{n}}{T_{e}} \right )^{2}=\left ( \frac{R_{n}}{R_{e}} \right )^{3}$

$\left ( \frac{T_{n}}{1} \right )^{2}=\left ( \frac{4.5\times10^{9}}}{1.5\times10^{8}}} \right )^{3}$

Tn = 164.32 earth years

Thus, the neptune year is equal to 164.32 earth year.

Answer:

$x = - \frac{25}{3}$

Step-by-step explanation:

$\frac{10}{3} = \frac{x}{( - \frac{5}{2}) }$

<h3>i) simplify the complex fraction</h3>

$\frac{10}{3} = - \frac{2x}{5}$

<h3>ii) simplify the equation using cross multiplication</h3>

$5(10) = - 2x(3)$

$50 = - 6x$

<h3>iii) swap the sides of the equation</h3>

$- 6x = 50$

<h3>iv) divide both sides of the equation by -6</h3>

$\frac{ - 6x}{ - 6} = \frac{50}{ - 6}$

$x = - \frac{50}{6}$

<h3>v) simplify the fraction</h3>

$x = - \frac{25}{3}$
