Which statement is true about a number and its additive inverse?

Mathematics

Answer: Option D

Their sum is always zero

Step-by-step explanation:

Given any number x, the additive inverse of x is -x.

For example, the additive inverse of 3 is - 3, the additive inverse of 2.2 is -2.2.

In this way, note that adding a number with the additive inverse of this number will always result in the number zero.

x + (-x) = 0

Therefore, the correct option is option D

Answer:

Option D is correct.

Step-by-step explanation:

The additive inverse of a number is the same number with the negative sign

i.e. if we have a number 1 then it's additive inverse would be -1

So if we add both the number and its additive inverse the answer would be zero.

1+(-1) = 0

So, Option D their sum is always zero is correct.

1/2 cm x 3/2cm x 7/4cm... Find the volume
forsale [732]
Remember, to the find the volume, you have to do length*width*height.

So it would be 7/4 * 3/2 * 1/2

To answer this, multiply all the numerators together, and multiply all the denominator together.

This would be:

21/16



So the answer is 21/16 cm^3 or 1.3125 cm^3.


Hope this helps. If you have any questions, place it in the comment section below.

PLEASE HURRY! When two fractions less than 1 are divided, is their quotient always, sometimes or never greater than 1? Explain.
beks73 [17]
Answer: Sometimes

Explanation:

Quotient greater than 1:

3/4 divide by 2/3
= 3/4 x 3/2 = 9/8 > 1

4/5 divide by 2/5
= 4/5 x 5/2 = 2 > 1

Quotient less than 1

1/100 divide by 2/10
= 1/100 x 10/2 = 1/20 < 1

1/50 divide by 1/25
= 1/50 x 25/1 = 1/2 < 1

Which of the following theorems cannot be used to prove two lines are<br> parallel?
mariarad [96]

Answer:

Option H

Step-by-step explanation:

Option F

If two lines are cut by a transversal so that a pair of corresponding angles are congruent, then the lines are parallel.

True.

Option G

If two lines are cut by a transversal so that a pair of alternate exterior angles are congruent, then the lines are parallel.

True

Option H

If two line are cut by a transversal so that a pair of vertical angles are congruent, then the lines are parallel.

Since, vertical angles don't prove the lines cut by a transversal are parallel.

So the statement is False.

Option J

If two lines are are cut by a transversal so that a pair of same side interior angles are supplementary, then the lines are parallel.

True.
