Additive inverse of 125 is – 125, option C is correct.

Solution:

Given that , a number is 125

We have to find the additive inverse for the above given number from the above given set of options.

Now, we know that, sum of a number and its additive inverse equals to 0.

So, let us check option by option.

Option A:

Given number is -(-125)

-(-125) ⇒ 125 + ( - ( - 125 ) )

⇒ 125 + 125

⇒ 250 ⇒ wrong option

Option B:

Given number is 125

⇒ 125 + 125 ⇒ 250 ⇒ wrong option

Option C:

Given number is -125

125 + ( - 125 ) ⇒ 125 – 125 ⇒ 0 ⇒ correct option

Hence, additive inverse of 125 is – 125, option C is correct

The sum of two positive integers, a and b, is at least 30. The difference of the two integers is at least 10. If b is the greate

KIM [24]

a + b ≥ 30, b ≥ a + 10, the system of inequalities could represent the values of a and b

option A

Step-by-step explanation:

Here we have , The sum of two positive integers, a and b, is at least 30. The difference of the two integers is at least 10. If b is the greater integer, We need to find which system of inequalities could represent the values of a and b . Let's find out:

Let two numbers be a and b where b>a . Now ,

The sum of two positive integers, a and b, is at least 30

According to the given statement we have following inequality :

⇒ $a+b\geq 30$

The difference of the two integers is at least 10

According to the given statement we have following inequality :

⇒ $b-a\geq 10$

⇒ $b-a+a\geq 10 +a$

⇒ $b\geq 10 +a$

Therefore , Correct option is A) a + b ≥ 30, b ≥ a + 10

How to write 5/9 + 5/9 as a mixed number

velikii [3]

Answer:

You add the numerators so 5 + 5 is 10. So its 10/9. We only added the numerators because the denominators were the same. So then 10/9 simplified by minusing 9 from ten because ten is the denominator the answer is:

1 1/9
