can these three angles 47, 84, and 56 create a triangle​

Answer:

400.7 cm^3

Step-by-step explanation:

Answer:

roots are [(5 - [tex]\sqrt{73}[/tex]) / 4] and [(5 + [tex]\sqrt{73}[/tex]) / 4]

Step-by-step explanation:

[-b ± √b² - (4ac)] ÷2a

2x² - 5x - 6 = 0

a = 2

b = -5

c = -6

[5 ± √5² - 4(2)(-6)] ÷ 2(2)

[5 ± √25 - (-48)] ÷ 4

[5 ± √73] ÷ 4

Answer:

59 degrees

Step-by-step explanation:

If BCG is 40 degrees and AGC is 19 degrees, you would add the 2 angles to find AGB giving you 59 degrees.

Answer:

y = 8x + 25

Step-by-step explanation:

Using the coordinates (10, 105) and (20, 185)

The standard linear equation is expressed as y = mx+c

m is the slope

c is the intercept

m = 185 - 105/20-10

m = 80/10

m = 8

Get the y-intercept

Since y = mx+c

105 = 8(10) + c

105 = 80 + c

c = 105 - 80

c = 25

Get the required equation

Recall that y = mx+c

y = 8x + 25

Hence the required equation is y = 8x + 25

Answer:

y = -13

I like two step equations

Step-by-step explanation:

Equation :

18 = 5-y

Im just going to flip it around because it feels more comfortable

5-y = 18

Add y to both sides

5 = 18 + y

Subtract 18 from both sides

-13 = y

y = -13

Answer:

x = 1, y = 3

Step-by-step explanation:

Given:

x - y = -2

2x + y = 5

First, add y on both sides for the first equation.

x = y - 2

Then, plug in x into the second equation.

2(y -2) + y = 5

2y - 4 + y = 5

3y = 9

y = 3.

Next, now that you've found y, plug it into either the first or second equation to solve for x. I'll be using the second equation.

2x + 3 = 5

2x = 2

x = 1.

Ans: x = 1, y = 3

'is' means =

so

X =

so

3X + Y = P

3X = P - Y

X = (P - Y) ÷ 3

Answer:

63.5, 66.5

Step-by-step explanation:

Approximately 68% of Camden's finishing times fall within the interval from 63.5 seconds to 66.5 seconds.

The empirical rule states that for a normal distribution, approximately 68% of the data lies within one standard deviation of the mean, approximately 95% of the data lies within two standard deviations of the mean, and approximately 99.7% of the data lies within three standard deviations of the mean.

Since we want to find the interval that represents the middle 68% of Camden's finishing times, we need to find the range of times that are one standard deviation above and below the mean.

The mean of Camden's finishing times is 65 seconds, and the standard deviation is 1.5 seconds, so the interval that represents the middle 68% of his finishing times is:

[65 - 1.5, 65 + 1.5] = [63.5, 66.5] seconds

This means that approximately 68% of Camden's finishing times fall within the interval from 63.5 seconds to 66.5 seconds.

Write in standard form.

2 x  −  3 y  =  − 21

Write in standard form.

3 x  +  y  =  23

answered: faith1993

Standard form means, move the variables to the left-hand-side and leave the constant all by herself on the right-hand-side, usually sorting the variables, so"x" goes first.

now, there's a denominator, we can do away with it, by simply multiplying both sides by the denominator, so let's do so,

answered: evelynalper08

The standard form of an equation of a line is written as:

Ax + By = C  

where A, B and C are constants.

y = –2/3x + 7  

2/3x + y = 7

(2/3x + y = 7)3

2x + 3y = 21

The standard form of an equation of a line is written as:

Ax + By = C  

where A, B and C are constants.

y = –2/3x + 7 2/3x + y = 7(2/3x + y = 7)32x + 3y = 21

Y= -2/3*x+7 | *3

3y= - 2x+21    | +2x

3y+2x=21  this is the correct answer

You multiply everything by 3 which equals 3y=2x+21 then you switch 21 and 3y which equals -21=2x-3y. Hope this helps

1 Answer. The equation in standard form is 23x−y=7 .

Step-by-step explanation:

answered: Guest

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

\frac{2}{5}=\frac{x-18}{x}

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

Answer:

Step-by-step explanation:

In order to solve for x, she had to first subtract 6 on both sides of the equation.  Then divide by 5 on both sides of he equation.  After the division part, she was able to successfully isolate x.

The equation she had to solve was     (C)  5x+6=21

First step:  Subtracting 6 on both sides of equation resulted in

5x = 15

Second step:  Dividing both sides of the equation by 5 resulted in

x = 3

Answer:

The data for Dr. Amine's office is more

symmetrical than the data for Dr. Harris's office.

Step-by-step explanation:

Using visual inspection, Dr. Amine's office data is symmetrical as the median value is well. Positioned in between the box plot with approximately the same width to both left and right of the plot from the median value. While that of Dr. Harris office is clearly skewed.

From the median value and range values, Dr. Harris's office has greater value than Dr. Amine's office, hence the options are false. The interquartile range are also not the same.
