Further explanationDecimal numbers are numbers in which there are commas or decimal points.
The value of each number in decimal numbers is based on a comparison of the number 10
In a decimal system, the numbers have the following consecutive values (the place value of the digits in a number): hundred thousands, ten thousands, one thousands, hundreds, tens, ones, decimal points, tenths, hundredths, thousandths, ten thousandths , hundred thousandths
Between ones and tenth values separated by commas (decimal points)
Decimal numbers can also be expressed as proper or mixed fractions
The position of each digit in decimal numbers is important.
Because the decimal number is based on the number 10, As we move left, each position is 10 times bigger, and As we move right, each position is 10 times smaller
On the left of the decimal point is a whole number
"Equivalent to" mean having the same value.
In the decimal addition operation, we must pay attention to the place value
Addition between decimal numbers must be the same place value, for example between hundreds with hundreds, ten with ten and so on
Or if we use a vertical addition system, one under the other, pay attention to the decimal point, must be straight from top to bottom
In this addition operation we check the results of the addition of each decimal number operation
Question :3.7−6.4 = - 2.7
Answer choices :a. 6.4 + 3.7 = 10.1
b. 6.4 - 3.7 = 2.7
c. -6.4 + 3.7 = -2.7
d. - 6.4 - 3.7 = -10.1
Answer choices that have the same result is option C
Or simply this is the commutative form of addition operations
a + b = b + a (a = -6.4, b=3.7)
-6.4+3.7 = 3.7 +(-6.4)
-6.4+3.7 = 3.7 - 6.4

General Formula= b+ or - √b²-4ac/2a by substituting gives us
-14+ or - √0/2 so we have one answer because 4ac is to b2 and √0 = 0 -14/2 = -7 The answer is one solution -7. If you want and extra hint there it is: b²-4ac is called the discriminant because it shows you how many solutions the equation will have if it's positive then it's 2 solutions and if it's zero then it's one solution and if it's negative no solution because b²-4ac is under a root and if a negative number is under a square root then it's undefined.

what is the answer to -12x+13x
Answers
If this is hard for you to solve, just switch the numbers.
13x - 12x
This gives you 1x, so the answer will be simply x.
Since both numbers have the same variable (x), then all you need to do is add the numbers together, and totally just ignore the variable.
What is -12 + 13?
-12 + 13 = 1
So, -12x + 13x = x

Answers
The pressure of 1036.0 mb converts to 30.59 inches of mercury (in. Hg) using the conversion factor that 1 inch of Hg is approximately 33.8639 mb.
A pressure of 1036.0 mb (millibars) when converted to inches of mercury (in. Hg) is equivalent to 30.59 inches. This conversion is relevant in fields like meteorology and aviation where pressure readings are essential. To convert millibars to inches of mercury, one must use the conversion factor that 1 inch of Hg is approximately equal to 33.8639 mb. Therefore, the calculation would look like this:
Start with the given pressure: 1036.0 mb.Use the conversion factor 1 in. Hg = 33.8639 mb.Divide 1036.0 mb by 33.8639 mb/in. Hg to get the pressure in inches of mercury.1036.0 mb / 33.8639 mb/in. Hg = 30.59 in. Hg.This means the correct answer is B. 30.59 in.

Since we have given that
The slope intercept form of the equation of a line is given by
[tex]y=-x+6-------------------(1)[/tex]
Line passing through a point is given by
(-3,8)
So, from the equation (1), we get that
m = Slope of line = -1
So, Point slope form of the equation of the line is given by
[tex]y-y_0=m(x-x_0)\\\\(y-8)=-1(x+3)\\\\y-8=-(x+3)[/tex]
Hence, the point slope form of the equation for this line is given by
