Answer:

Step-by-step explanation:

Your steps in order would be ...

__

Executing these steps, we get ...

  4(3x -20) = 16 . . . . . add x

  3x -20 = 4 . . . . . . . . divide by 4

  3x = 24 . . . . . . . . . . .add 20

  x = 8 . . . . . . . . . . . . . divide by 3, giving the solution

_____

Additional comment

If you were to distribute the 4 first, you would have ...

  12x -80 -x = 16 -x

Now, you can add x and add 80 to get ...

  12x -80 = 16

  12x = 96

Then dividing by 12 gives ...

  x = 8

You will notice that these steps do not match steps available in your list.

Answer:

Yes

Step-by-step explanation:

Yes. 72 divided by 4 would be 18, so it is a factor

Answer:

Yes

Step-by-step explanation:

Yes because 4 x 18 = 72

72 divided by 18 = 4

I know this because if you multiply 4 x 18 you will get 72. To check you can do the inverse operation, which is division, so with that being said,  72 divided by 18 = 4.

I explained to so you can have a better understanding. Have a great day!

Answer:

∠ B = 123°, ∠ D = 57°

Step-by-step explanation:

Each lower base angle is supplementary to the upper base angle on the same side.

∠ A and ∠ D are on the same side, then

6x + 12 + 2x + 20 = 180

8x + 32 = 180 ( subtract 32 from both sides )

8x = 148 ( divide both sides by 8 )

x = 18.5

Thus

∠ A = 6x + 12 = 6(18.5) + 12 = 111 + 12 = 123°

∠ D = 2x + 20 = 2(18.5) + 20 = 37 + 20 = 57°

The lower base angles and the upper base angles are congruent, so

∠ B = ∠ A = 123°

∠ C = ∠ D = 57°

Answer:

Step-by-step explanation:

#1). It could be good to provide us with the picture, because the answer depends from the angle we choose for letter A.

--- If angle A is acute, then m∠A = m∠D

and

6x + 12 = 2x + 20 ⇒ x = 2

m∠A = m∠D = 24°

m∠B = m∠C = 180° - 24° = 156°

--- If angle A is obtuse, then m∠A + m∠D = 180°

and

6x + 12 + 2x + 20 = 180 ⇒ x = 18.5

m∠A = m∠B = 6(18.5) + 12 = 123°

m∠D = m∠C = 2(18.5) + 20 = 57°

#2). 12k + 5 = 145

12k = 140

k = [tex]\frac{35}{3}[/tex] = [tex]11\frac{2}{3}[/tex]

Answer:

1:u

Step-by-step explanation:

Grey slabs = 1/5 of total slab

Say total slab = x

Then,

Grey slabs = 1x/5

We can represent

Yellow slabs = u/5

Then ratio of Grey to yellow would be;

Gray slabs / Yellow slabs = (1x/5)/(u/5)

=1/u

= 1:u

Since there are 55 slabs in total, then

Yellow slab would be = 55/5 = 11

Answer:

[tex]x=\dfrac{y}{0.62}[/tex]

Step-by-step explanation:

[tex]5\ \text{km}=3.1\ \text{miles}\\\Rightarrow 1\ \text{km}=\dfrac{3.1}{5}=0.62\ \text{miles}[/tex]

[tex]10\ \text{km}=6.2\ \text{miles}\\\Rightarrow 1\ \text{km}=\dfrac{6.2}{10}=0.62\ \text{miles}[/tex]

Let [tex]y[/tex] be the distance in miles. So distance in km is given by

[tex]x=\dfrac{y}{0.62}[/tex].

The equation that shows the approximate distance in kilometers as a function if the distance in miles is [tex]x=\dfrac{y}{0.62}[/tex].

[tex]f(x)=\dfrac1{x-1}=\dfrac1{x-1}+0[/tex]

x-1 = 0  for  x = 1

so:

Vertical asymptote: x = 1

Domain:  Dom f = R\{1}  {or: Dom f = (-∞, 1)∪(1, ∞)}

Horizontal asymptote:  y = 0

Range:    Ran f=R\{0}  {or: Ran f = (-∞, 0)∪(0, ∞)}

2.

[tex]f(x)=\dfrac{-1}{x}+4=\dfrac{-1}{x-0}+4[/tex]

x-0 = 0  for  x = 0

so:

Vertical asymptote: x = 0

Domain:  Dom f = R\{0}  {or: Dom f = (-∞, 0)∪(0, ∞)}

Horizontal asymptote:  y = 4

Range:    Ran f=R\{4}  {or: Ran f = (-∞, 4)∪(4, ∞)}

3.

[tex]f(x)=\dfrac{1}{x+3}-3[/tex]

x+3 = 0  for  x = -3

so:

Domain:  Dom f = R\{-3}  {or: Dom f = (-∞, -3)∪(-3, ∞)}

Horizontal asymptote:  y = -3

Range:    Ran f=R\{-3}  {or: Ran f = (-∞, -3)∪(-3, ∞)}

[tex]f(x)=\dfrac{-1}{x+5}-6[/tex]

x+5 = 0  for  x = -5

so:

Vertical asymptote: x = -5

Domain:  Dom f = R\{-5}  {or: Dom f = (-∞, -5)∪(-5, ∞)}

Horizontal asymptote:  y = -6

Range:    Ran f=R\{-6}  {or: Ran f = (-∞, -6)∪(-6, ∞)}

[tex]f(x)=\dfrac{-1}{x+1}+3[/tex]

x+1 = 0  for  x = -1

Horizontal asymptote:  y = -2

Range:    Ran f=R\{-2}  {or: Ran f = (-∞, -2)∪(-2, ∞)}

Answer:

c= 7 p=4

Step-by-step explanation:

3p + 4c = $40

therefore  

15p + 20c = 200

5p + 2c = 34

therefore

15p + 6c = 102

14c = 98

98/14=7

c = 7

5p + 2(7) = 34

5p + 14 = 34

- 14 - 14

5p = 2020/5= 4

p = 4

Answer:

The equation of the graphed line is:

Step-by-step explanation:

From the graph, it is clear that the line is a horizontal line at y = 2.

We know that a horizontal line has a slope of 0 because the value of y does not change no matter what the value of x we put in.

In other words, the equation of the horizontal line would always get the form:

y = k

where k is the y-intercept of the line.

Determining the y-intercept of the line:

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 2

Thus, the y-intercept k = 2

Thus, if we substitute the y-intercept k = 2 in the equation y = k, we get the equation

y = 2

Therefore, the equation of the graphed line is:

Given:

[tex]R^2=0.92,a=8000,b=0.9[/tex].

Exponential regression model is

[tex]y_1\sim a(b)^{x_1}[/tex]

To find:

The exponential regression representing the population of Lazy Town as a function of time in years.

Solution:

We have, [tex]a=8000,b=0.9[/tex].

Exponential regression model is

[tex]y_1\sim a(b)^{x_1}[/tex]        ...(i)

Putting [tex]a=8000[/tex] and [tex]b=0.9[/tex] in (i), we get.

[tex]y_1\sim 8000(0.9)^{x_1}[/tex]

Thus, [tex]y_1\sim 8000(0.9)^{x_1}[/tex] is the required exponential regression representing the population of Lazy Town as a function of time in years.

Answer:

12, 6 and 30

Step-by-step explanation:

Step one:

given data

Number of medals = 48 medals

The given ratio is = 2:1:5

The total ratio is = 2+1+5= 8

Step two;

Applying the part to all method

for Gold we have

2/8=x//48

cross multiply

8x= 48*2

divide both sides by 8

x= 96/8

x= 12

gold is 12

for silver we have

1/8=x//48

cross multiply

8x= 48*1

divide both sides by 8

x= 48/8

x= 6

silver is 6

for bronze we have

5/8=x/48

cross multiply

8x= 48*5

divide both sides by 8

x= 240/8

x= 30

Bronze  is 30

Answer:

Florida became a territory of the United States.

Step-by-step explanation:

i got it right on Edge

The correct option for the given statement is Florida became a territory of the United States.

Adams-Onís TREATY:-

The Adams-Onís Treaty between the United States and Spain was negotiated by Secretary of State John Quincy Adams and the Spanish Minister to the United States, Don Luis de Onís, and signed in February 1819.

The principal elements in the treaty were the acquisition of Florida by the United States and the establishment of a boundary line between Spanish territory and the United States.

After the Louisiana Purchase in 1803, Pres. Thomas Jefferson argued that Florida was included in Louisiana. In 1810 and 1812 the United States annexed sections of West Florida.

In the treaty Spain gave East and West Florida to the United States, and the United States agreed to assume claims by citizens of the United States against Spain.

Hence, the answer is Florida became a territory of the United States.
