The value of m is 5/3 .

Step-by-step explanation:

=> 9m -4 = 6 + 3m.

=> 9m - 3m = 6 + 4.

=> 6m = 10.

=> m = 10/6.

=> m = 5/3 .

Answer:

The pentagon shape = 8

The star shape = 6

The curl shape = 3

The wave pattern shape = 5

Step-by-step explanation:

Let the pentagon shape = w, the star shape = x, the curl shape = y, and the wave pattern shape = z

Horizontally, we have;

w + 2·x + y = 23.....(1)

2·y + 2·z = 16...........(2)

2·z + w + x = 24.. ..(3)

3·y + x = 15..............(4)

Vertically, we have;

2·x + z + y = 20.......(5)

2·y + w+ z = 19........(6)

From the above equations, we have;

From equation (4), we have x = 15 - 3·y

From equation (2), we have z = 8 - y

From equation (1), we have w = 23 - (2·(15 - 3·y) + y)

∴ w = 23 - 30 + 6·y - y = 5·y - 7

w = 5·y - 7

Substituting the above values for x, and z i equation (5) gives;

2·x + z + y = 2·(15 - 3·y) + 8 - y + y = 20

30 - 6·y + 8 - y + y = 20

6·y = 30 + 8 - 20 = 18

y = 18/6 = 3

y = 3

w = 5·y - 7 = 5×3 - 7 = 8

w = 8

z = 8 - y = 8 - 3 = 5

z = 5

x = 15 - 3·y = 15 - 3×3 = 15 - 9 = 6

x = 6

Therefore, we have;

w = The pentagon shape =8

x = The star shape =6

y = The curl shape = 3, and

z = The wave pattern shape =5

The number of each of the four given shapes filled in the rows and columns are;

8 inscribed pentagon shape

6 star shapes

3 spiral shapes

5 Waves inside rectangle shape

From the diagram, we see four shapes and so let us identify them with letters;

Inscribed pentagon shape = a

Star shape = b

Spiral shape = c

Waves inside rectangle shape = d

For the first row, we see 2 stars, one inscribed pentagon and one spiral shape. Thus;

a + 2b + c = 23   .....(eq 1)

For the second row, we see 2 spiral shapes and 2 Waves inside rectangle shape. Thus;

2c + 2d = 16  ......( eq 2)

For the third row, we see 1 star, one inscribed pentagon  and 2 Waves inside rectangle shape. Thus;

a + b + 2d = 24 ....(eq 3)

For the fourth row, we see 3 spiral shapes and one star shape. Thus;

b + 3c = 15 ....(eq 4)

Looking at the columns, we see that;

First column;

2c + a + d = 19  ....(eq 5)

Second column, we have;

2b + c + d = 20  .....(eq 6)

From eq 4; b = 15 - 3c

From eq 2, we have; d = 8 - c

Putting them in eq 1 gives;

a + 2(15 - 3c) + c = 23

a + 30 - 6c + c = 23

a = 5c - 7

Putting d = 8 - c and a = 5c - 7 into eq 5 gives;

2c + 5c - 7 + 8 - c = 19

6c + 1 = 19

6c = 18

c = 3

Put 3 for c in a = 5c - 7

a = 5(3) - 7

a = 8

Put 3 for c in b = 15 - 3c

b = 15 - 3(3)

b = 6

Put 3 for c in d = 8 - c

d = 8 - 3

d = 5

Thus, we have;

8 inscribed pentagon shape

6 star shapes

3 spiral shapes

5 Waves inside rectangle shape

Answer:

1st one

Step-by-step explanation:

The inequality that is not correct for x = 2.7 will be x + < 9. The correct option is A.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Given that the value of x is 2.7. Check all the options for x = 2.7.

Option A:-

x + 14 < 9

x < 9 - 14

x < -5  False

Option B:-

x - 4 < 0

Answer:

-1/10

Step-by-step explanation:

Answer:

-1/10

Step-by-step explanation:

First you need a common demonator of 10

so

-1/2 --> -5/10

and  -2/5 --> -4/10

using this the equation is:

-5/10 - (-4/10) which equals

-5/10 + 4/10= -1/10

Answer:

The average cost of a movie ticket in Japan is $17.86 and the average cost of a movie ticket in Switzerland is $13.75

Step-by-step explanation:

The question seems to be incomplete. Here is a similar question and the solution:

Average movie prices in the United States​ are, in​ general, lower than in other countries. It would cost  ​$81.08 to buy three tickets in Japan plus two tickets in Switzerland. Three tickets in Switzerland plus two tickets in Japan would cost  $76.97. How much does an average movie ticket cost in each of these countries?

Step-by-step explanation:

Let the cost of tickets in Japan be $x and the cost of tickets in Switzerland be $y.

From the question,

It would cost  ​$81.08 to buy three tickets in Japan plus two tickets in Switzerland. That is

3x + 2y = 81.08 ...... (1)

Also from the question,

Three tickets in Switzerland plus two tickets in Japan would cost  $76.97. That is

2x + 3y = 76.97 ...... (2)

Multiply equation (1) by 2, so that we get

6x + 4y = 162.16 ...... (3)

and multiply equation (2) by 3, so that we get

6x + 9y = 230.91 ...... (4)

Now, Subtract equation (3) from equation (4), we get

5y = 68.75

y = 68.75/5

y = 13.75

Put the value of y into equation (1) to determine x

3x + 2y = 81.08

3x + 2(13.75) = 81.08

3x + 27.5 = 81.08

3x = 81.08 - 27.5

3x = 53.58

x = 53.58/3

x = 17.86

∴ x = 17.86 and y =13.75

Hence, the average cost of a movie ticket in Japan is $17.86 and the average cost of a movie ticket in Switzerland is $13.75.

Answer:

98.1°F ≤ x ≤ 99.1°F

Step-by-step explanation:

Given the function:

f(x) = |98.6 - x|

Variance = 0.5

98.6°F - x = ± 0.5

Lower bound :

98.6 - 0.5 ≤ x

98.1 ≤ x

Upper bound :

x ≤ 98.6 + 0.5

x ≤ 99.1

Hence,

98.1°F ≤ x ≤ 99.1°F

Answer:

C

Step-by-step explanation:

[tex]\frac{d}{dx} (8x^-1)\\-8x^{-2}\\[/tex]

using x = -3

[tex]-8(-3)^{-2}\\\frac{-8}{9}[/tex]

The instantaneous slope of the function y = 8/x at x = -3 is -8/9.

Option C is the correct answer.

We have,

To find the instantaneous slope of the function y = 8/x at x = -3, we can differentiate the function with respect to x.

Differentiating y = 8/x using the power rule, we get:

dy/dx = -8/x²

Now, we can evaluate the instantaneous slope at x = -3 by substituting the value into the derivative:

dy/dx = -8/(-3)²

= -8/9

Therefore,

The instantaneous slope of the function y = 8/x at x = -3 is -8/9.

Answer:

5/12

Step-by-step explanation:

i just looked it up...

====================================================

Explanation:

Multiply top and bottom of 5/8 by 3 to get 15/24

This means 5/8-5/24 is the same as 15/24-5/24

The denominators are the same, so we can subtract the numerators to have them placed over the common denominator

15/24 - 5/24 = (15-5)/24 = 10/24

Then we reduce by dividing each part of the fraction by the GCF 2

10/2 = 5

24/2 = 12

Meaning that 10/24 = 5/12

Note how multiplying top and bottom of 5/12 by 2 leads to 10/24 again.

So overall,

5/8 - 5/24 = 5/12

Answer:

The answer is 3.

Step-by-step explanation:

If you divide a negative by a negative, then it equals a positive, because the two negatives cancel out.

So, -15/-5 = 3.

But, if it were -15/5 = ?

Then it would be -3, because there is only one negative, therefore it cannot cancel out.
