Do 5 A,B for 10 points.

Answers

Answer 1

Answer:

X = C - By over A which also is A ≠ 0

Y = C - Ax over B which is also B ≠ 0

Step-by-step explanation:

Solve for x

First subtract "By" from both sides:

Ax + By - By = C - By

Then simplify,

Ax = C - By

Divide both sides by A:

Ax / A = C/A - By/A ; A≠0

Then simplify:

X = C - By over A ; A ≠ 0.

-------------------------------------

Solve for y

First subtract "Ax" from both sides:

Ax - By - Ax = C - Ax

Simplify,

By - C = Ax

Then divide both sides by B:

By/B = C/B - Ax/B ; B ≠ 0

Simplify:

Y = C-Ax / B ; B ≠ 0.

Hope this helps have a good day! :)

The Russian ice breaker ,yamal, can move forward through 2.3-meter-thick ice at a speed of 5.5 kilometers per hour. Write and solve a multiplication equation to find the number of hours it will take to travel 82.5 kilometers through the ice(Remember, I'm in sixth grade , so answer so I can understand it)

Answers

The train travels at 5.5km per hour.

We know that in x hours it will advance by x*5.5 km.

Hence we need to solve x*5.5=82.5, hence x=82.5/5.5=15

It will take 5 hours

Answer: It will take 5 hours.

What happens to the volume of a cone when the height is doubled ?

Answers

Answer-

When the height is doubled, the volume of the cone also gets doubled.

Solution-

Volume of a cone is given by,

$V=(\pi * r^2* h)/(3)$

Where,

V = Volume,

r = radius of the base,

h = height of the cone.

Let, height at first be x, then volume would be,

$V_1=(\pi * r^2* x)/(3)$

As the height is doubled, so height = 2x, then volume would be,

$V_2=(\pi * r^2* 2x)/(3)\n\n=2* (\pi * r^2* x)/(3)\n\n=2* V_1$

Therefore, when the height is doubled, the volume of the cone also gets doubled.

if the value of the volume of the cone let says the radius is 1 and the height is 2. Then the volume is 2pi. If the height is now 4, then it just doubled.
