Which variable is incorrect in his solution?It follows from the task content that the equation is to be solved for y.
Given; A = 2x -xyz² -w
Add w-2x to both sides of the equation;
A+w-2x = -xyz²
Divide both sides by; -xz²

express 121,200 in exponential (powers of 10) notation. express the earth sun distance in kilometers in powers of 10 notation.
1.5·10⁸ kilometers
As a result, the Earth Sun distance is 150 million kilometers. To use scientific notation, pick a value between 1 and 10, then multiply it by 10ˣ.
So the number between 1 and 10 in 150,000,000 is 1.5, with 8 decimal points.
As a result, the solution is 1.5·10⁸
State the distance between The Earth and The Sun?
The benefits of Earth's prime placement in the solar system are numerous. We are just far enough away from the Sun for life to thrive.
Venus is excessively hot. Mars is quite chilly. Scientists refer to our region of space as the "Goldilocks Zone" because it looks to be ideal for life.
As previously stated, Earth's average distance from the Sun is around 93 million miles (150 million kilometers). That's one AU.
On this hypothetical scale, these so-called "linebackers" resemble minuscule specks rather than the massive linebackers of the NFL.
If all of the known asteroids in our solar system were combined, their total mass would be less than 10% that of Earth's moon.

A model of a golf course says that hole #9 is 175 yards long. If the scale for the model is 2in.:20 yards, how many inches are there between the tee and the hole on the model.
There is 17.5 inches distance between the tee and the hole on the model.
According to the question we have been given that
length of hole#9 is = 175 yards
the scale for the model is given as = 2 inch : 20yards
We need to find the inches between the tee and the hole.
Let the length between the tee and the hole on the model be x inches
Thus the above condition can be written as
2 inches / 20yards = x inches/175 yards
We have to solve this proportion for x we get
x inches = 175*2/20
x = 17.5 inches
Hence there is 17.5 inches distance between the tee and the hole on the model.

From the given graph, we have that:
The ordered pairs are given as follows: (-5,2), (-3,0), (0,-3), (3,-6), (5, -8).
The table is given by:
x = -5, g(x) = 2.x = -3, g(x) = 0.x = 0, g(x) = -3.x = 3, g(x) = -6.x = 5, g(x) = -8.In function notation, we have that:
g(-5) = 2, g(-3) = 0, g(0) = -3, g(3) = -6, g(5) = -8.
How to get the ordered pairs from the graph of a function?To get the ordered pairs from the graph of a function, we have to:
Get the x-coordinate, that is, the value of the point on the horizontal axis.Get the y-coordinate, that is, the value of the point on the vertical axis.An ordered pair has the following notation: (x,y).
Hence, from the points on the graph, the ordered pairs are given as follows:
(-5,2), (-3,0), (0,-3), (3,-6), (5, -8).
How to write the ordered pairs in the table?To write the table from each ordered pair (x,y), we have that y = g(x), hence:
x = -5, g(x) = 2.x = -3, g(x) = 0.x = 0, g(x) = -3.x = 3, g(x) = -6.x = 5, g(x) = -8.How to write the function notation?We take the g(x) points from the table, replacing x by it's numeric value, hence:
g(-5) = 2, g(-3) = 0, g(0) = -3, g(3) = -6, g(5) = -8.

1. G=J+2
A=U*2

U+10-10=8+10 ==> Add 10 on both sides to single out U.
U=18
A=U*2
A=18*2
A=36
J=A+U-26
J=36+18-26
J=54-26
J=28
G=J+2
G=28+2
G=30
T=G/3 - 2
T=30/3 - 2
T=10-2
T=8 ==> 8 years old
2. 8+x=18
8-8+x=18-8
x=10 years
3. U=18
18+5=23 years old
4. G=J+2
G=J*2
J*2=J+2
2J=J+2
J=2 ==> subtract J on both sides

there were twice as many four-door cars as two-door cars in the parking lot. there were 36 cars in the lot. how many had four doors? how many had two doors?
the number of two door cars in the parking lot is 12 and the number of four door cars in the parking lot are 24.
We are given that the number of four door cars in a parking lot is equal to twice the two door cars.
Let the two door cars be x
Four door cars = 2 x
Also, we are given that total cars = 36
So, we get the equation:
x + 2 x = 36
3 x = 36
x = 36 / 3
x = 12
Two door cars = x = 12
Four door cars = 2 x = 2 ( 12) = 24
