Which of the following expressions are equivalent?

Answer:

x = -3/7

Step-by-step explanation:

(2x-2)/x-3 = 5/6

(2x-2)×6 = 5×(x-3)

12x-12 = 5x-15

12x-5x = -15+12

7x = -3

x = -3/7

Final answer x is equal to -3/7.

Answer:

The figure below is the graph of this basic function. Graph of y=x^2.

The ratio shows how many times one value is contained in another value.

The number of cups of strawberries Valerie used is 6 cups.

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

The ratio of strawberries to melons is 3:4.

Let us consider,

Strawberries = 3x

Melons = 4x

Now,

A total of 14 cups of fruit were made.

This means,

14 = 3x + 4x

14 = 7x

x = 2

Now,

The number of cups of strawberries is 3x.

3x = 3 x 2 = 6 cups

The number of cups of melons is 4x.

4x = 4 x 2 = 8 cups.

We see that,

6 cups + 8 cups = 14 cups.

Thus,

The number of cups of strawberries Valerie used is 6 cups.

Given:

Volume of a square base pyramid = 48 cubic inches.

Area of base = 36 sq. inches.

To find:

The height of the pyramid.

Solution:

Volume of a pyramid is

[tex]V=\dfrac{1}{3}Bh[/tex]

Where, B is the base area and h is the height of the pyramid.

Putting V=48 and B=36, we get

[tex]48=\dfrac{1}{3}(36)h[/tex]

[tex]48=12h[/tex]

[tex]\dfrac{48}{12}=h[/tex]

[tex]4=h[/tex]

Therefore, the height of the pyramid is 4 inches.

Answer:

O They are similar triangles.

Step-by-step explanation:

Given

Triangle X

[tex]\angle A = 30[/tex]°, [tex]\angle B = 90[/tex]°,  [tex]\angle C = 60[/tex]°

[tex]AB = 3,\ BC = 4,\ AC = 5.[/tex]

Triangle Y

[tex]\angle A = 30[/tex]°, [tex]\angle B = 90[/tex]°,  [tex]\angle C = 60[/tex]°

[tex]AB = 9,\ BC = 12,\ AC = 15.[/tex]

Required

The relationship between X and Y

From the given parameters, the corresponding angles of both triangles are equal i.e.

A = A, B = B and C = C

However, the side lengths are not equal.

The side lengths of Y is 3 multiplied by the side lengths of X.

This is shown below:

Triangle X

[tex]AB = 3,\ BC = 4,\ AC = 5.[/tex]

Multiply by 2 to get Triangle Y

[tex]AB= 3 * 3 = 9[/tex]

[tex]BC= 4 * 3 = 12[/tex]

[tex]AC = 5 * 3 = 15[/tex]

Since side lengths are not equal, but they have a common ratio of 3, then the triangles are similar.

Step-by-step explanation:

There are not equivalent to each other because the equation 2x+5=9 is equivalent to 2x=4

Answer: no.

Step-by-step explanation: 2x + 5 = 9 so subtract 5 from each side you get 2x = 4

X= 2

If we substitute that back in 2(2) + 5 = 9 so

If you do -2(2) = 4 it’s -4=4 and it’s not equivalent to each other

Answer:

4, 16

Step-by-step explanation:

[tex] a_n = 3a_{n - 2} - a_{n - 1} - 1 [/tex]

Let's see if it works for a_3:

[tex] a_3 = 3a_{1} - a_{2} - 1 [/tex]

[tex] a_3 = 3(3) - (4) - 1 [/tex]

[tex] a_3 = 4 [/tex]

Yes, it works for a_3.

Now let's calculate a_4.

[tex] a_4 = 3a_{2} - a_{3} - 1 [/tex]

[tex] a_4 = 3(4) - (4) - 1 [/tex]

[tex] a_4 = 7 [/tex]

a_4 is also correct.

Let's calculate a_5.

[tex] a_5 = 3a_{3} - a_{4} - 1 [/tex]

[tex] a_5 = 3(4) - 7 - 1 [/tex]

[tex] a_5 = 4 [/tex]

Let's calculate a_6.

[tex] a_6 = 3a_{4} - a_{5} - 1 [/tex]

[tex] a_6 = 3(7) - 4 - 1 [/tex]

[tex] a_6 = 16 [/tex]

Answer: 4, 16

Answer:

half

Step-by-step explanation:

I got this answer by doing (22/7-2/3) and (22/7-2/3)/2 and comparing the results.

(22/7-2/3) = 52/21, which is about 2.47.

(22/7 - 2/3)/2 = 26/21, which is about 1.23.

With this, you can conclude that it would be half the value.
