Answer:

the mean is 8

Step-by-step explanation:

added them all together and divided by 7

The mean of numbers will be 8.

What is Addition?

The process of combining two or more numbers is called the Addition.

Given that;

The numbers are,

⇒ 5,6,12,2,5,12,14

Now,

Since, The numbers are,

⇒ 5,6,12,2,5,12,14

Hence, The mean = 5 + 6 + 12 + 2 + 5 + 12 + 14 / 7

                             = 56/7

                             = 8

Thus, The mean of numbers will be 8.

Using PEMDAS we would do the multiplication and division first and then the subtraction. So 4*5 = 20 and 8/2 is 4 so therefore 20-4 is 16.

Answer:

PEMDAS (Multiply and divide, then add and subtract)

Step-by-step explanation:

Multiply 4 and 5 to get 20-8/2

Divide 8 by 2 to get 20-4

subtract to get 16

Answer:

D, 6m

Step-by-step explanation:

Step one:

Given data

The volume and base area of a rectangular cargo container is 720 cubic

= 720m^3

The area of the cargo container is 120 m^2

Required

We want to find the height of the container

Step two

The expression  for the volume is given as

Volume= Area* height

so,

720= 120*h

divide both sides by 120

720/120= h

h= 6 m

The height is 6m

Answer:

The answer would be 28 becasue if you divide th right number by the m substitue that for the number 97

The sum of the expressions for n = -2 and m = 5 is -43

We have the following expressions (3m + 2n − 6) and (− 4 − 6m + 7n).

We can write the sum of the expression as -

(3m + 2n − 6) + (− 4 − 6m + 7n)

3m + 2n - 6 - 4 - 6m + 7n

3m - 6m + 2n + 7n - 6 - 4

- 3m + 9n - 10

At n = - 2 and m = 5, we get -

(- 3 x 5 + 9 x -2 - 10)

- 15 - 18 - 10

- 43

Therefore, the sum of the expressions for n = -2 and m = 5 is -43.

Answer:

D

Step-by-step explanation:

A is incorrect because if 1 x value corresponds to multiple y values, it is not a function

B is incorrect for the same reason as a

C is incorrect because it is linear

D is correct because 1.) all of the others are wrong, and 2.) it is nonlinear.

Answer:  The answer is -3

Step-by-step explanation:

The graph goes down 3 and over 1, since slope is written rise/run, it would be -3/1, which reduces to -3

Answer:

C

Step-by-step explanation:

Step-by-step explanation:

Solve the inequality for b

-15b <= 45 divide both sides by -15, since you're dividing by a negative number switch the direction of the sign.

b >= -3

So, your number line is all values of b greater than or equal to -3. Since it is including -3, the circle will be filled and increase to the positive.

Answer:

subtract 9x from both sides

Step-by-step explanation:

10x = 6 + 9x

9x             9x

19x = 6

0.315789474 = x

.315 = x

Answer:

Subtract 9x from both sides of the equation.

Step-by-step explanation:

To put x by itself, you need to first put all like terms together. So in order to do this, you need to put 10x and 9x together. Since 9x is positive, you need to subtract 9x from both sides of the equation.

Here is how you completely solve the equation:

Isosceles triangle

Step-by-step explanation:

The given sides of a triangle are 8 cm, 5 cm and 8 cm.

We need to say that the type of triangle.

The two sides of a triangle are same i.e. 8 cm and the other side is 5 cm.

Such type of triangle in which two sides are equal, the triangle is isosceles. Here, two sides are 8 cm and the third one is 5 cm. It means the triangle is an isosceles triangle.

Answer: y=1/2x-1

Step-by-step explanation:

Answer:

p=−12x2+8x+−492

is what I got

The value of p must be 7 for the expression (x - p)2 + 5 equivalent to the expression x2 – 14x + 54.

Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.

To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.

It is given that the expression (x - p)2 + 5 equivalent to the expression x2 – 14x + 54

That is (x - p)^2 + 5 = x^2 – 14x + 54

Solving for p;

x^2 + p^2 + 5 - 2px =  x^2 – 14x + 54

Combine the like terms;

p^2 + 5 - 2px =– 14x + 54

p^2 - 2px + 14x - 49 = 0

If we put p = 7 then

49 - 14x + 14x - 49 = 0

Therefore, the value of p must be 7 for the expression (x - p)2 + 5 equivalent to the expression x2 – 14x + 54.

Answer:

50c + 120m represents Mia's earnings with c commercials and m movies

Mia would earn $610 with 5 commercials and 3 movies

Step-by-step explanation:

First, create an expression that represents her earnings with c commercials and m movies:

50c + 120m will represent her earnings with c commercials and m movies

Now, find her earnings with 5 commercials and 3 movies:

50c + 120m

50(5) + 120(3)

= 250 + 360

= 610

So, Mia would earn $610

Answer:

$610

Step-by-step explanation:

Ok so I would multiply $50 with 5 because it costs $50 for one commercial and there are 5 of them. You get $250 from it.

Next you multiply $120 and 3 because it costs $120 for 3 movies. You get $360.

Now you add and you get your answer which is $610.

Answer:

Miley can walk a distance of [tex]13\frac{1}{5}[/tex] miles in four hours.

Step-by-step explanation:

Given that:

Distance walked by Miley in [tex]1\frac{2}{3}[/tex] hours = [tex]5\frac{1}{2}[/tex] miles

We will find unit rate in term of hours.

[tex]\frac{5}{3}\ hours = \frac{11}{2}\ miles[/tex]

Multiplying both sides by 3/5

[tex]\frac{3}{5}*\frac{5}{3}\ hour = \frac{11}{2}*\frac{3}{5}\\\\Unit\ rate = \frac{33}{10}\miles\ per\ hour[/tex]

Distance walked in four hours = [tex]4*\frac{33}{10}\ miles[/tex]

Distance walked in 4 hours = [tex]\frac{66}{5}=13\frac{1}{5}\ miles[/tex]

Hence,

Miley can walk a distance of [tex]13\frac{1}{5}[/tex] miles in four hours.

[tex]x = 20^{\circ}[/tex]

[tex]\angle A = 150^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]\angle A = 8x - 10[/tex]

[tex]\angle B = 3x + 90[/tex]

See attachment

From the attachment A and B are vertically opposite.

This implies that:

[tex]\angle A = \angle B[/tex]

Substitute values for A and B

[tex]8x - 10 = 3x + 90[/tex]

Collect Like Terms

[tex]8x - 3x = 10 + 90[/tex]

[tex]5x = 100[/tex]

Solve for x

[tex]x = \frac{100}{5}[/tex]

[tex]x = 20^{\circ}[/tex]

Substitute 20 for x in [tex]\angle A = 8x - 10[/tex]

[tex]\angle A = 8 * 20 - 10[/tex]

[tex]\angle A = 150^{\circ}[/tex]
