Given:
A number is 400.
To find:
The additive inverse of 400.
Solution:
We know that the sum of a number and its additive inverse is 0.
If "a" is number and "b" is its additive inverse, then
Let x be the additive inverse of 400. Then,
Subtract both sides by 400.
Therefore, the additive inverse of 400 is .
Answer:
Step-by-step explanation:
First, begin by multiplying by its reciprocal.
To do this, flip the fraction upside-down.
The resulting equation looks like this:
Cancel out the two 27's and you are left with , which you can simplify to q.
Next, multiply -3 by . Remember, what you do on one side, you must do on the other.
Your equation should look like this:
The final answer is .
