Mathematics

Answer:

When solving for a variable, you undo all operations done to that variable.

In the equation 6x - 3 = -51 we see on the left-hand side that the variable x is being multiplied by 6 and subtracted 3 times.

We can reverse the subtraction operation by using the inverse of subtraction.

Which is the addition operation. If we add 3 to the left-hand side, the -3 term will disappear.

But wait! Anything we do on one side we must do also on the opposite side.

6x - 3 + 3 = -51 + 3

6x             = -48

Now how can we undo the multiplication operation done to x?

We can use division. It will make the 6 coefficient disappear!

6x / 6 = -48/6

x = -8

<h3>So, x is equal to -8. (C) </h3>

What is the value of x to the nearest tenth?
jenyasd209 [6]
The segment of length x bisects the chord of length 19.2.
The diameter is 24, so the radius is 12.
You have a right triangle with hypotenuse 12, and one leg 19.2/2 = 9.6

9.6^2 + x^2 = 12^2

92.16 + x^2 = 144

x^2 = 51.84

x = 7.2

Given that circumference of a circle is 44m. Calculate it's area​
dimaraw [331]

Answer:

Area=154.062 m^{2}

Step-by-step explanation:

As Circumference of a circle is given by;

C=2\times \pi\times r

As the circumference is 44m so we can calculate the value of r by using the above formula.

44=2\times \pi \times r\\\\\frac{44}{2\pi} =r\\\\\implies r=\frac{22}{\pi} =7.003 m

Now to Calculate the Area of a Circle.

As the area of a circle is,

Area =\pi \times r^{2}\\ Area=\pi \times (7.003)^{2} \\Area=\pi \times 49.039\\Area=154.062m^{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 :)
