The property of equality applied to solve the equation is division property of Equality.
What is the property of equality?Property of equality says that by performing any mathematical operation, of both sides of an expression does not change the original value of the equation.
The equation given in the problem is,
[tex]0.36 x = -1. 8[/tex]
This equation is solved further by dividing both side of the expression with decimal number 0.36 as,
[tex]\dfrac{0.36}{0.36}x = -\dfrac{1. 8}{0.36}\\x=-5[/tex]
Here, the division operation is performed both sides of the equation to solve the equation. This does not change the original value of the equation and gives the value of unknown number.
Thus, the property of equality applied to solve the equation is division property of Equality.

Answer:
The radicals is the name of the sign we use in roots. The numerator is the power of the exponential, and the denominator is the power of the root.
So we take the radical:
√((-4)^2/7)
And move the denominator to the place where we list the root's power:
7√((-4)2)
Do note you can remove the outermost parentheses if you were to extent the radical's top line, something like so:

A mole starts out in its burrow 5.1 feet below the surface of the ground. It digs straight up at a rate of 0.4 feet per minute.
How long does it take for the mole to reach a depth of -3.7 feet?
Enter your answer as a decimal in the box.
The mole approximately 3.5 minutes to reach a depth of -3.7 feet.
To determine how long it takes for the mole to reach a depth of -3.7 feet, we need to calculate the time it takes to cover the distance between its starting point and the target depth.
The mole is digging straight up at a rate of 0.4 feet per minute.
Since the target depth is negative, we can consider it as a negative displacement.
The distance the mole needs to travel can be calculated as follows:
Distance = Target depth - Starting depth
Distance = -3.7 feet - (-5.1 feet)
Distance = -3.7 feet + 5.1 feet
Distance = 1.4 feet
Now, we can calculate the time it takes for the mole to cover this distance using the formula:
Time = Distance / Speed
Time = 1.4 feet / 0.4 feet per minute
Time = 3.5 minutes
Therefore, the mole approximately 3.5 minutes to reach a depth of -3.7 feet.

The coordinates of a rectangle are (-11,20), (-11,3), (-1,20), (-1,-3). Find the perimeter and the area of the rectangle.
Answer:
The perimeter of the rectangle is 54, and the area is 170.
Step-by-step explanation:
First, we must plug the coordinates into a graph (attached below).
[tex]l=10\\w=17[/tex]
Now, we must solve for the perimeter.
[tex]P=2(l+w)\\P=2(10+17)\\P=2*27\\P=54[/tex]
Lastly, we must solve for the area.

The measure of x is an illustration of the cosine trigonometry ratio
The measure of x to the nearest tenth of a degree is 58.7 degrees
How to calculate the measure of xThe measure of x is calculated using the following cosine ratio
[tex]\cos(x) = \frac{4.1}{7.9}[/tex]
Evaluate the quotient
[tex]\cos(x) = 0.5190[/tex]
Take the arccos of both sides of the equation
[tex]x = \cos^{-1}(0.5190)[/tex]
Evaluate the arccos(0.5190)
[tex]x = 58.73[/tex]
Approximate to the nearest tenth of a degree
[tex]x = 58.7[/tex]

2 box plots. The number line goes from 175 to 450. For resort A, the whiskers range from 175 to 375, and the box ranges from 250 to 300. A line divides the box at 375. For Resort B, the whiskers range from 200 to 400, and the box ranges from 300 to 375. A line divides the box at 325. Kevin wanted to go snowboarding for his vacation. He looked up annual snowfall of both resorts over a ten-year period to determine which resort would have the better snowfall. Compare the two box plots and use the drop-down menus to determine where Kevin should plan to go for vacation. What is the approximate median snowfall at Resort A? What is the approximate median snowfall at Resort B?.
Box plot 5 important descriptive measures about data that they represent.
The median snowfall for Resort B is greater than the median for Resort A
The interquartile range has higher values for Resort A than for Resort B.
Resort B has more snowfall overall than Resort A does.
How does a boxplot show the data points?
A box plot has 5 data descriptions.
The leftmost whisker shows the minimum value in the data.
The rightmost whisker shows the maximum value in the data.
The leftmost line in the box shows the first quartile.
The middle line shows the median, also called the second quartile.
The last line of the box shows the third quartile.
How to find the interquartile range?IQR(interquartile range) is the difference between the third and first quartile.
Inferring the information each box plot describe, we get:
Case 1: For resort A:
Wisker's minimum value = minimum value for resort A = 175
Maximum value = 375
Box's minimum value = First quartile = 250
Box's maximum value = Third quartile = 300
First quartile = 250 < Median = Second quartile < 300 = third quartile
Thus, 250 < Median for resort A < 300
IQR = Third quartile - first quartile = 300 - 250 = 50
Range of values = Max - min = 375 - 175 = 200
Case 2: For resort B:
Wisker's minimum value = minimum value for resort B = 200
Maximum value = 400
Box's minimum value = First quartile = 300
Box's maximum value = Third quartile = 325
First quartile = 300 < Median = Second quartile < 375 = third quartile
Thus, 300 < Median for resort B < 375
IQR = Third quartile - first quartile = 325 - 300 = 25
Range of values= Max - min = 400 - 200
Thus, it is visible that:
Median for resort A < 300 < Median for resort B
or
Median for resort A < Median for resort B.
and
IQR for resort A = 50 > IQR for resort B = 25
and
Both have the same variation as both ranges are the same, which is the interval of values assumed for both resorts.
Hence, Minimum, maximum, first, and third quartile all are smaller for resort A, thus, Resort B has more snowfall overall than Resort A does.

Which point is located at (2, -3)?
Point K because its x-coordinate is at 2 and its y-coordinate is at -3.
A) Point K
Answer:
Point K
Step-by-step explanation:
Remember, in a rectangular coordinate plane, every point is shown as (x, y)
x is moving left and right while y moves up and down. Looking at the point provided, (2, -3).
x = 2
A positive x value means the point will be shifted to the right, while the number 2 tells you to shift to the right 2 units.
y = -3
A negative y value means the point will be shifted down, while the number -3 tells you to shift down 3 units.
Now, looking at the graph, starting at (0, 0), move to the right 2 units and move down 3 units. The point resting at this point is Point K.

5x+3y=15
x+2y= -5 solve for x and y
Answer:
x=-3/5y+3
Step-by-step explanation:
Let's solve for x.
5x+3y=15
Step 1: Add -3y to both sides.
5x+3y+−3y=15+−3y
5x=−3y+15
Step 2: Divide both sides by 5.
5x/5 = -3y+15/5

can 3 meters and 2 km be expresses as a ratio.
Answer:
yes, you can just write it as 3m : 2km
Step-by-step explanation:
I don't know if this is completely right, but I know you can also turn 3m into km by multiplying it by 1000, (because there are 1000 m in every km) and then solve because 3000km/2km = 1500km
So to solve would be 1500 km. I hope the first answer is right though. Did I help? Let me know in the comments
