Answer:

Answer: Option B.

Step-by-step explanation:

Hey there!!

Let's simply solve it.

Given,

[tex] \frac{1}{2} x + \frac{1}{4} x = 16[/tex]

Now, take LCM.

[tex] \frac{2x + x}{4} = 16[/tex]

Multiply 16 by 4.

[tex]3x = 16 \times 4[/tex]

or, 3x = 64.

Divide 64 by 3.

[tex]x = \frac{64}{3} [/tex]

x= 21.33

Therefore, your answer is option B.

Hope it helps...

Answer:

Step-by-step explanation:

-2 (x -4) - 1/2 (3-4x) = -12

                ×(-2)           ×(-2)

4(x - 4) + (3 - 4x) = 24

4x - 16 + 3 - 4x = 24

Answer:

The player's vertical jump ability is 15 inches

Step-by-step explanation:

The mark on the scale which the player's hand can reach while standing = 4-in which is the standing reach

The mark on the scale the player's hand can reach when jumping = 19-in

Therefore, the player's vertical jumping ability is given as the difference between the height the players hand can reach when jumping and the height which the player's hand can when standing,

Which gives;

The player's vertical jump ability = 19 inches - 4 inches = 15 inches

The player's vertical jump ability = 15 inches.

Answer:

[tex]\huge\boxed{\sf \frac{34}{9}\ \ OR \ \ 3\frac{7}{9} }[/tex]

Step-by-step explanation:

Let

x = 3.777.......                (1)

Then

10x = 37.777.....             (2)

Subtracting (1) from (2)

10x - x = 37.7777..... - 3.77777.......

9x = 34

Dividing both sides by 9

x = 34 / 9

x = [tex]3 \ \frac{7}{9}[/tex]

[tex]\rule[225]{225}{2}[/tex]

Answer: 66

Step-by-step explanation:

Answer:

30 cm.

Step-by-step explanation:

We can solve this problem by making a proportion:

1 cm/65 km = x cm/1,950 km

By cross-multiplying, we can solve for x:

65x = 1,950

x = 30

Answer:

3x - 6

Step-by-step explanation:

To evaluate f(2x) and f(x + 2) substitute x = 2x and x = x + 2 into f(x)

f(2x) = 3(2x) - 2 = 6x - 2

f(x + 2) = 3(x + 2) - 2 = 3x + 6 - 2 = 3x + 4

Thus

f(2x) - f(x + 2)

= 6x - 2 - (3x + 4)

= 6x - 2 - 3x - 4

= 3x - 6

Answer:

The answer isn't in the options anyway I'll write it. the answer is 46.

Step-by-step explanation:

According to BODMAS rule - addition should be done first so

4+36= 40 and -3 +7 = 4 so 40+4 ,= 44

then we should do subtracting so, 10-8 = 2

to conclude we should bring the equation to an end so,

44+2 = 46

Answer:

Part A: 0

Part B: All real numbers

Step-by-step explanation:

Part A:

We have:

[tex](6^2)^x=1[/tex]

First, let's evaluate the square:

[tex]36^x=1[/tex]

Now, what to the xth power will equal 1?

Remember the fact that anything (except for 0) to the zeroth power is 1.

Therefore, our x is 0:

[tex]36^0=1[/tex]

Part B:

We have:

[tex](6^0)^x=1[/tex]

Like mentioned previously, anything to the zeroth power is 1. Thus:

[tex]1^x=1[/tex]

Now, 1 is a special base because 1 to any (real) power is still going to be 1. For example:

[tex]1^0=1,1^1=1,1^{999},\text{ and } 1^{\pi}=1[/tex]

Therefore, our values of x is all real numbers.

And we're done!

Answer:

0

Step-by-step explanation:

To find the slope, we use the slope formula

m = (y2-y1)/(x2-x1)

    = ( 4-4)/( 5 - -3)

    = 0/ ( 5+3)

   = 0/8

  = 0

Answer:

Step-by-step explanation:

65 inches is the diameter  of the screen

We have a right triangle for a tv with the side length of 16x and 9x

Using the Pythagorean theorem

a^2 +b^2 = c^2

(16x)^2 + (9x)^2 = 65^2

256x^2+ 81x^2 = 4225

Combine like terms

337x^2 = 4225

Divide each side by 337

x^2 =4225/37

Take the square root of each side

x =65sqrt(337)/337

x =3.54077562

The width is 16 times this

width =56.65240991

height is 9 times this

height = 31.86698058

Ok amigo, entonces es falso porque los miles son 5 ahora, la parte 25 está en la marca de diez mil más inteligente, por favorStep-by-step explanation:

Multiply/divide both sides by the same non-zero constant. Therefore, option A is the correct answer.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, A) 5x=20 and B) x=4.

Here, 5x=20

Divide both sides by the same non-zero constant 5, we get

5x/5 =20/5

x=4

Therefore, option A is the correct answer.
