Answer:

v=15

Step-by-step explanation:

31+4v+44=9v

Answer:

v = 15

Step-by-step explanation:

By exterior angle theorem:

9v° = 31° + (4v + 44)°

9v° = (4v + 44 + 31)°

9v = 4v + 75

9v - 4v = 75

5v = 75

v = 75/5

v = 15

Answer:

x=8

Step-by-step explanation:

add 1 to each side

x/2-1=3

    +1  +1

x/2=4

multiply each side by 2 to isolate the varible

x/2=4

 x2  x2

x=8

The equivalent expressions are:

x² + 11x + 18

2x² + 7x - 4

x² - 10x + 25

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

(x + 2) (x + 9)

(x + 4) (2x - 1)

(x - 5)²

Now,

Applying the distributive property.

1)

(x + 2) (x + 9)

x² + 9x + 2x + 18

x² + 11x + 18

2)

(x + 4) (2x - 1)

2x² - x + 8x - 4

Combining the like terms.

2x² + 7x - 4

3)

(x - 5)²

(x - 5) (x - 5)

x² - 5x - 5x + 25

x² - 10x + 25

Thus,

The equivalent expressions are:

x² + 11x + 18

2x² + 7x - 4

x² - 10x + 25

Answer:

-3(22-d) ?

Step-by-step explanation:

I hope this is right please let me know

Sum of interior angles of a △ = 180°

∴ ∠T + ∠V + ∠U = 180°

⇒ 37° + 63° + X° = 180°

⇒ X° + 100 = 180°

⇒ X° = 180° - 100°

⇒ X° = 80° (D).

1500 words in 20 minutes

Step-by-step explanation:

So 225/3 min

or 225:3

so to find unit rate just divide

225/3=75

75 per minute

Now 75 words per minute times 20 minutes75*20=1500

So 1500 words in 20 minutes

Answer:

Let one number be x and the other be (x-5)

Step-by-step explanation:

x^2+(x-5)^2=193

x^2+x^2-10x+25=193

2x^2-10x+25=193

Subtract 193 from both sides of the equation.

2x^2-10x-168=0

x=12 or x=-7

x-5=7 or x-5=-12

The linear equation containing the points (0.5, 10) and (-4.5, -10) will be:

Please check the attached graph also.

Step-by-step explanation:

Given the points

Finding the slope between (0.5, 10) and (-4.5, -10)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0.5,\:10\right),\:\left(x_2,\:y_2\right)=\left(-4.5,\:-10\right)[/tex]

[tex]m=\frac{-10-10}{-4.5-0.5}[/tex]

Refine

[tex]m=4[/tex]

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

substituting the values m = 4 and the point (0.5, 10)  in the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 10 = 4(x-0.5)[/tex]

Add 10 to both sides

[tex]y-10+10=4\left(x-0.5\right)+10[/tex]

Simplify

[tex]y=4x+8[/tex]

Therefore, the linear equation containing the points (0.5, 10) and (-4.5, -10) will be:

Answer:

By the Empirical Rule, 68% of the data would be between 19.8 and 28.2

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 24

Standard deviation = 4.2

What percentage of the data would be between 19.8 and 28.2

19.8 = 24 - 4.2

28.2 = 24 + 4.2

So within one standard deviation of the mean

By the Empirical Rule, 68% of the data would be between 19.8 and 28.2
