Which statements include two quantities in the real world that are additive inverses?

Select each correct answer.

Juana drove 25 miles east and then drove 25 miles west.

An elevator goes up 10 stories and then goes down 10 stories.

A chlorine ion has 17 positively charged protons and 18 negatively charged electrons.

Daniela opens a bank account and then deposits $200.

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:

This means the correct answer is B. 30.59 in.

The original price of the soft drink machine was $600, obtained by using the percentage reduction formula to find that $90 represents 15% of the original price.

To find the original price of the soft drink machine before the 85% reduction, we first need to understand what a percentage reduction means. An 85% reduction implies that the final price is only 15% of the original price, as 100% - 85% = 15%. Therefore, the $90 you paid is 15% of the original price.

Next, we will step through the following calculation to determine the original price:

Therefore, the original price of the soft drink machine was $600.

−6.4+3.7  is equivalent to 3.7−6.4

Decimal 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

3.7−6.4 = - 2.7

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

D. [tex]17 + 2x[/tex]

Explanation:

The associative property is defined as a grouping of multiplication, addition, subtraction and division.

[tex]\boxed{a + \left( {b + c} \right) = \left( {a + b} \right) + c}[/tex]

In commutative property we interchange the numbers or digits.

This property can be used for multiplication and addition. It cannot be used in division and subtraction.

Commutative property for addition is [tex]\boxed{x + y = y + x}[/tex]

The expression is [tex]3.7 - 6.4.[/tex]

[tex]A = 3.7 - 6.4[/tex]

By commutative property of addition the expression can also be expressed as follows,
