Please help with the question above????

Answer:

Step-by-step explanation:

12x - 4 = 5x + 24

First subtract 5x from both sides

That's

12x - 5x - 4 = 5x - 5x + 24

7x - 4 = 24

Add 4 to both sides

That's

7x - 4 + 4 = 24 + 4

7x = 28

Divide both sides by 7

We have the final answer as

Hope this helps you

Answer:4

Step-by-step explanation:First, add 4 to both sides of the equation. Then subtract 5x from both sides. Finally, divide both sides by 7.

Answer:

x=b-10

Step-by-step explanation:

any is in a word problem means = and less than means subtract. I am only 90% sure this answer is correct but using my logic this is what I got.

The number that is b less than 10 will be given in the mathematical form as n = b - 10.

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Express using algebra: The number that is b less than 10. Let the number be n. Then the equation is given as,

n = b - 10

The number that is b less than 10 will be given in the mathematical form as n = b - 10.

Answer:

D. 136°

Step-by-step explanation:

[tex]\because \overrightarrow{EC} \:bisects \: \angle BED. \\

\therefore m\angle BEC = m\angle DEC\\

\therefore (11x+2)\degree = (8x+20)\degree \\

\therefore 11x + 2 = 8x + 20\\

\therefore 11x - 8x = 20-2\\

\therefore 3x = 18\\

\therefore x = \frac{18}{3}\\

\therefore x = 6\\\\

\because m\angle BED= m\angle BEC + m\angle DEC\\

\therefore m\angle BED= (11x+2)\degree + (8x+20)\degree\\

\therefore m\angle BED= (19x+22)\degree \\

\therefore m\angle BED= (19\times 6+22)\degree \\

Answer:

x = [tex]\frac{23}{a}[/tex]

Step-by-step explanation:

Given equation is,

ax + 3 = 23

To solve this equation for the value of x isolate the variable 'x' on the one side of the equation.

Step 1,

Subtract 3 from both the sides of the equation.

ax + 3 - 3 = 23 - 3

ax = 20

Step 2,

Divide the equation by a,

[tex]\frac{ax}{a}=\frac{23}{a}[/tex]

x = [tex]\frac{23}{a}[/tex]

Therefore, x = [tex]\frac{23}{a}[/tex] will be the answer.

Answer:

11.9 au

Step-by-step explanation:

The orbital period of Jupiter around the sun is 11.9 years.

Here, we have,

To solve this question, we need to understand the concept of Kelper's Third Law and how to use it.

we know that,

Kelper's Third Law:

Kelper's Third Law posits that the ratio between the square of the orbital period (T) as well as the average distance cube of a planet away from the Sun is constant for all planets circling the Sun.

T²/r³ = constant

Suppose, we make a reference to Earth, we have:

T_e²/r_e³ = T_j²/r_j³

Making the orbital period (T_j) of Jupiter as the subject, we have:

T_j = √T_e² * r_j³ /r_e³

where;

r_e = avg. distance from earth to sun = 1 au

so, calculating we get,

T_j  = 11.9 years.

Answer:

-2

Step-by-step explanation:

I took the quiz.

The scale factor of the dilation is -2.

Dilation of a figure will leave its sides get scaled (multiplied) by same number. That number is called the scale factor of that dilation.

It's also called scaling of a figure, but due the involvement of coordinates, it involves a center of a dilation, which is like a pinned point which stays at same place after dilation.

It's like we enlarge or shorten the size of the figure (or keep it same, when scale factor = 1).

Given that Under a dilation centered at the origin, the vertex, (−2, 4), of a polygon is moved to the point (4, −8) .

Then the scale factor of the dilation

(-2k , 4k )= (4, −8)

Thus, -2k = 4

k = -2

Hence, the scale factor of the dilation is -2.
