which expression is equivalent to -1/4(20z + 24)

A. 5z-24
B. -5z-6
C. 5z+24
D. -5z+6

Answer:

Step-by-step explanation:

I'm not sure this task part of geometry or trigonometry.

Now, the solution with trigonometry functions

[tex]\frac{x}{\sqrt{3} }[/tex] = cos 30°

[tex]\frac{x}{\sqrt{3} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex]

x = [tex]\frac{\sqrt{3} *\sqrt{3} }{2}[/tex] = [tex]\frac{3}{2}[/tex]

Answer:

(-3b) (10a -3b)

Step-by-step explanation:

(5a–3b)^2–25a^2

Replace (5a–3b) with x

x^2 - (5a) ^2

We have the difference of squares

( x-5a) (x+5a)

Now replace x with (5a -3b)

(5a -3b -5a) ( 5a -3b +5a)

Combine like terms

(-3b) (10a -3b)

Answer:

(5a-3b)²-25a²

= 25a²+9b²-2×5a×3b-25a { (a-b)²= a²+b²-2ab}

=9b²-30ab

=3b(3b-10a)

= -3b(10a-3b)

Answer:

2x+6y=-2 x is -3y-1 and 5x-3y=31 x is 3y+31/5

Step-by-step explanation:

5x−3y=31

Add 3y to both sides.

5x=31+3y

The equation is in standard form.

5x=3y+31

Divide both sides by 5.

5

5x =  5

3y+31

​Dividing by 5 undoes the multiplication by 5.

x=  5

3y+31

Answer:

take 11 to rhs

-3x = 44 - 11

-x = 33/3

-x = 11

x = -11

Answer: Subtract 11 on both sides

Step-by-step explanation:

11 - 3x = 44

-11        -11

-3x = 33

Divide by -3 on each side

x=-11

There's all of the steps, I know you didn't ask. I hope I helped!

Answer:

(x,y) -> (x-4, y+2)

Step-by-step explanation:

it is translated 4 to the left and 2 up

Answer:

8. (Refer to explanation)

Step-by-step explanation:

Factors of 16 and 24:

16:

1 x 16

2 x 8

4 x 4

Factors of 16 are 1, 2, 4, 8 and 16

24:

1 x 24

2 x 12

3 x 8

4 x 6

Factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24.

How to find common factor?

To find the common factor, you need to list out the factors and if a factor which is the same number appears from both 16 and 24, it is known as a common factor.

Common factors of 16 and 24 are 1, 2, 4, 8. Since greatest common factor is the number which is a common factor but is the biggest number, the answer is 8.

Answer:

[tex]Probability = \frac{1}{9}[/tex]

Step-by-step explanation:

Given

Toppings: Pico de gallo, Onions and Steak

Required

The probability of getting Onions and Steak

The probability is calculated using:

[tex]Probability = P(Onion)\ and\ P(Steak)[/tex] --- because the events are independent

[tex]P(Onion) = \frac{n(Onion)}{Total}[/tex]

[tex]P(Onion) = \frac{1}{3}[/tex]

[tex]P(Steak) = \frac{n(Steak)}{Total}[/tex]

[tex]P(Steak) = \frac{1}{3}[/tex]

So, we have:

[tex]Probability = P(Onion)\ and\ P(Steak)[/tex]

[tex]Probability = P(Onion)\ *\ P(Steak)[/tex]

[tex]Probability = \frac{1}{3} * \frac{1}{3}[/tex]

[tex]Probability = \frac{1}{9}[/tex]

Answer:

The field will not fit

Step-by-step explanation:

To find the angle, we will use cosine rule;

c² = (a² + b² - 2abcosC)

C in this case is θ

Thus;

15² = (8² + 20² - 2(8 × 20)cos θ)

225 = (64 + 400 - 320cos θ)

464 - 225 = 320cos θ

cos θ = 239/320

θ = cos^(-1) 0.7469

θ = 41.68°

Thus angle is not less than 40° as recommended. Thus, the field will not fit.

Step-by-step explanation:

9x - 8 = 6x + 4

3x - 8 = 4

3x = 12

x = 4

Answer:

9x - 6x = 4 + 8

3x = 12

x = 12÷ 3

x = 4

Step-by-step explanation:

restamos las variables, verificamos que 9x es mayor que 6x por lo cual lo trasladamos al lado del 9x. Lo cual sería 9x menos 6x , por el lado del menos ocho y el cuatro, al menos ocho lo volvemos positivo lo cual da 4 más 8. y así

9x - 6x = 4 + 8

3x = 12

x = 12÷ 3

x = 4

[tex]-\frac{x}{3} + 9[/tex]

Step-by-step explanation:

Answer:

x=65°

Step-by-step explanation:

Next to x would be 70. (180-110=70).

Since this is an equilateral triangle, the other angle is also 70.

180-70-70=40, so the third angle is 40.

Since this is a right angle, the other angle is 50 (90-40=50).

Since that is 50, and this is an equilateral triangle, the other two angles have to be the same.

180-50=130

130÷2=65

Answer:

Step-by-step explanation:

The imaginary lines connecting the home, the grocery store and the library form a right triangle with the distance from the home to the library being a hypotenuse.

Use Pythagorean to find the distance:

Step-by-step explanation:

Answer: 26

Step-by-step explanation:

10^2 + 24^2 = c^2

100 + 576 = 676

sqrt of 676 = 26

Answer:

f=26

Step-by-step explanation:

So its a right triangle so we can use the Pythagorean theorem since we’re finding sides. We got 2 sides already which is 10 and 24. Follow the formula of a^2+b^2=c^2. In this case we don‘t have the hypotnuse and only the a and the b so we plus them in. 10^2+24^2=c^2.

10^2=100

24^2=576

Add them up and get 676

FInd the square root of 676

√676= 26
