-4r + 8 = 8 - 4r

0 = 0 so it's like {}

Answer:

r = 0

Step-by-step explanation:

This is actually the first time I've actually had a equation with the variable equaling 0.

so first things first you have the equation:

r + 8 - 5r = 2(4 - 2r)

so you are going to add or multiply all the variable numbers together and the none variable numbers together like so:

r + (-5r) and (2*4) and (2* (-2r)) to get the equation looking like so:

8+ (-4r)= 8 -4r

you then add -4r to both sides to get this equation:

8+ ( -4r)= 8 -4r

    + 4r       +4r

8 = 8 + r

you then subtract 8 from both sides to get r:

8 = 8 + r

-8  -8

0 = r

to check substitute the 0 into r in the equation:

r + 8 - 5r = 2(4 - 2r)

0 + 8 - (5*0) = 2(4- (2*0))

8 = 8

Tada!!!

Answer:

True

Step-by-step explanation:

According to the Triangle Inequality, the sum of any two sides of a triangle has to be greater than the third side. 12+19 = 31 which is more than 30 so a triangle can have sides of 12, 19 and 30.

Answer:

y= 3/2x+ 360

Step-by-step explanation:

3/2 is the slope

360 is the b (y intercept)

Answer:

slope m = -60

equation y = -60x + 360

Step-by-step explanation:

to find slope use two points given

(x1, y1) = (6, 0)

(x2, y2) = (0, 360)

m = (360-0) / (0-6) = -60

equation y = mx + b

b is the y intercept at (0,360), b= 360

y = -60x + 360

Step-by-step explanation:

Answer:

C. x = 8

Step-by-step explanation:

We know that x · x · x is equal to 512. We know it cannot be negative because then the 512 would be negative. -2 x -2 x -2 is -8. -2 x -2 is 4. We know it cannot be B x = -6 or D. x = -8.

Let's multiply 6 x 6 x 6.

                           36 x 6 = 216.

Let's multiply 8 x 8 x 8.

                          64 x 8 = 512

The answer would be C. x = 8.

I hope that this helps! :)

Answer:

8

Step-by-step explanation:

x³ = 512

x³ = 8³

Cube root on both sides,

x = 8

Answer:

C=$0.33L-$43.76

I hope this is good enough:

Your answer would be 0.6, 3/5, and 6% are the 3 same portion. But, when they're all changed to a decimal they would equal to 0.6.

Triangle is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

The exterior angle is equal to the sum of the interior angles in a given triangle.

The measure of the other remote interior angle is 60°.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Let the measure of the other interior angle = M

The exterior angle is equal to the sum of the interior angles in a given triangle.

An exterior angle of a triangle has a measure of 80°, and one of the remote interior angles has a measure of 20°.

This means,

M + 20 = 80

Solve for M.

M + 20 = 80

Subtract 20 on both sides.

M = 80 - 20

M = 60

Thus,

The measure of the other remote interior angle is 60°.

Answer:

y=3/2x+5/2

Step-by-step explanation:

I used the Y2-Y1/X2-X1

In this equation you can see that there are 2 points (-5,-5) and (1,4)

If you substitute, you will get

4+5/1+5

9/6 and if you simplify this, you will get 3/2

Now that we have the slope, we just have to use y=mx+b

(I'm using the point (1,4))  4=3/2(1)+b

                                         4=3/2+b

                                         5/2=b

to work this out you need to solve for your y-intercept. by using what you have.

once you do so you get the answer y=1/2x+3

Answer:

2³×3²

Step-by-step explanation;

Prime Numbers are numbers which which have only two factors the number itself and one

Examples of Prime Numbers are;

2,3,5,7,11,13,17,19,23,29,etc

To Find The Prime Factorization Of The Number 72 you'll need to follow this;

72=2×36(we have the number 36 because when it's multiplied by 2 the product is 72 and 36 is not a prime number so it has to be broken down but since 2 is a prime number you leave it as it is)

72=2×2×18(we have 2×18 because because it's give us the product of 36 when multiplied so now that we have a second prime number(2) we will have to continue to break down the number 18)

72=2×2×2×9( We again have two another 2 and 9 here because when multiplied by each other its product is 18 so as we can see 9 is not a prime number so we have to break it down but the 2 is a prime number so we let it be)

72=2×2×2×3×3( As we can see here, 3 and 3 is a prime number so nothing happens to it so we have broken the non-prime numbers down so now we have all the numbers as Prime Numbers)

So; 72=2×2×2×3×3

So we are going to count the twos and threes so as you can see we have three twos and we have two threes. Which makes our final answer;

2³×3²

So The Prime Factorization of 72 is; 2³×3²

Answer:

y=2/3x-7

Step-by-step explanation:

The slope intercept formula is

y=mx+b

(m) is the slope (rate of change)

(b) is the y intercept (where the line crosses the y axis [vertical])

We need to find the slope and the y intercept. First we will find the slope.

The formula for slope is y1-y2/x1-x2

In and ordered pair the first value is the (x) and the second is the (y).

(x, y)

We take the (y) of one of the given points and subtract the (y) of the second given point, then divide it by the (x) of one of the given points and the (x) of the other given point.

5-(-1)/8-4

Simplify.

5-(-1) =5+1= 6

8-4=4

6/4 Simplify

3/2 is our slope.

Now we apply out new slope into our y=mx+b

y=3/2x+b

Now we need to find the (b) which is the y intercept.

To do this we need to use one of our given points, you can choose either but for this I'll use (4, -1).

In this ordered pair 4 is the (x) and -1 is the (y)

So replace (y) with -1 and (x) with 4

-1=3/2(4)+b

Now solve as usual.

-1=6+b

subtract 6 from each side

-7=b

b=-7

Put our (m) and (b) into our formula.

y=2/3x-7 is our equation.
