Answer:

x = 2

Step-by-step explanation:

6x - 10 = - 3x + 8

6x + 3x = 8 + 10

9x = 18

x = 18/9

x = 2

Three moons are in the same circular orbit around a planet. The moons are each 120,000 kilometers from the surface of the planet
VladimirAG [237]

Answer:

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

MN is the diameter of the planet which is MN = 60000

AM and NC are the distance of moons from the surface of the planet.

AM = NC = 120000

Since, angle ABC is given as 90 degree, it means, line AC will pass from the diameter of the planet.

So, distance between moon A and moon C is =

AC=AM + MN + NC

AC = 120000+ 60000+ 120000

AC = 300000

Hence the distance between point A and point C is 300000 Km.   :   Answer

Hope it will help :)

The product of two rational numbers is (-28/81). If one of them is (-2/3), the find the other.
KatRina [158]

Answer:

The other rational number is \dfrac{14}{27}.

Step-by-step explanation:

First rational number is \dfrac{-2}{3}

Let other rational number is \dfrac{x}{y}

The product of two rational numbers is \dfrac{-28}{81}

According to question,

\dfrac{x}{y}\times \dfrac{-2}{3}=\dfrac{-28}{81}

Multiplying both sides by (-3/2) such that,

\dfrac{x}{y}\times \dfrac{-2}{3}\times \dfrac{-3}{2}=\dfrac{-28}{81}\times \dfrac{-3}{2}\\\\\dfrac{x}{y}=\dfrac{14}{27}

So, the other rational number is \dfrac{14}{27}.

Write the slope-intercept form of the equation of the line described below.
prisoha [69]

The equation of the line is y=-\frac{2}{5}x-5

Explanation:

Given that the line passes through the points (-5,-3)

The slope of the line is m=-\frac{2}{5}

We need to determine the equation of the line.

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

y-y_1=m(x-x_1)

Let us substitute the points (-5,-3) and the slope m=-\frac{2}{5} in the above formula.

Thus, we have;

y+3=-\frac{2}{5}(x+5)

Simplifying, we get;

y+3=-\frac{2}{5}x-2

Subtracting 3 from both sides of the equation, we get;

y=-\frac{2}{5}x-5

Hence, the equation of the line in slope - intercept form is y=-\frac{2}{5}x-5

Please help!!! I don’t get any of this can someone please explain what to do and how I can get my answer????

Its just a matter of subbing ur numbers into the formula given
1. d = rt
    when r = 144 and t = 18
    now we sub
    d = 144 * 18
    d = 2592 <==
2. d = rt
    when r = 56 and t = 3.5
    sub
    d = 56 * 3.5
   d = 196 <==

3. A = L * W
    when L = 2 ft and W = 15 inches....this one u have to convert to     inches...2 ft = 24 inches...so L = 24 and W = 15
    A = 24 * 15
    A = 360 in^2 <==

4. A = L * W
    L = 3m and W = 32 cm...have to convert to cm.....1 m = 100 cm...so 3 m = 300 cm
    A = 300 * 32
    A = 9600 cm^2 <==

u basically do the same for all the others....its just a matter of subbing and solving
