70 I believe is the correct answer
Estimation is a important skill to know when adding and subtracting decimals because if you estimate you have an idea on what your answer should be close to.
For example 4.68-2.38 could be 5-2 which is 3. 4.68-2.38 equals 2.3. 2.3 is close to 3.
Answer:
B. 30.526
Step-by-step explanation:
Just subtract.
58.20
-27.674
30.526
The answer is 35000. Because 2 significant figures means the 2nd number, in this case it is the number 4 and if we want to round off something, look at the next number, if more than 5 or 5, you must round up.
You move the decimal to the left three places, so it is 10³
2.5 * 10³
Hope this helped :)
