use the additive inverse to find −492.89−(−871.78).
To find the value of (-492.89) - (-871.78), we can use the additive inverse.
The additive inverse of a number is the number that when added to the original number equals zero.
So, the additive inverse of (-871.78) is 871.78.
Now, we can rewrite the expression as (-492.89) + (871.78).
To calculate this, we add the numbers:
-492.89 + 871.78 = 378.89.
Therefore, -492.89 - (-871.78) equals 378.89.
Subtract 24−(−15).(1 point) $$
To find the value of −492.89 − (−871.78) using the additive inverse, you need to change the subtraction into addition with the opposite sign value.
The additive inverse of a number is the number that, when added to the original number, equals zero.
So, the additive inverse of −871.78 is 871.78.
Now, you can rewrite the expression:
−492.89 − (−871.78) becomes −492.89 + 871.78.
When you add these two values, you get:
−492.89 + 871.78 = 378.89.
Therefore, −492.89 − (−871.78) is equal to 378.89.
To find the sum of -492.89 and -(-871.78) (negative additive inverse), you can use the property of additive inverses. The additive inverse of a number is the number that when added to it, gives a sum of zero.
In this case, the additive inverse of -871.78 is 871.78. To solve the expression -492.89 - (-871.78), you can rewrite it as -492.89 + 871.78.
Now, to add the numbers -492.89 and 871.78:
- Start by aligning the decimal points:
-492.89
+ 871.78
- Add the digits in the rightmost place value (hundredths place in this case), ignoring the signs:
-492.89
+ 871.78
------------
89
- Since 8 + 9 = 17, write down 7 and carry over 1 (since 17 is a two-digit number):
-492.89
+ 871.78
------------
789
- Now, move to the next place value (tenths place) and repeat the process:
-492.89
+ 871.78
------------
3789
- In the next place value (ones place), there are no numbers left in -492.89 to add. Simply copy over the remaining digits from 871.78:
-492.89
+ 871.78
------------
3789.89
Therefore, -492.89 - (-871.78) is equal to 3789.89.
