Well here is your first part...
3.56×10^-5
Its negative so go to the left:
=.00000356
Here is your second part...
4×10^4×3×10^4
There both positive so go to the right
=40000 =30000
Then you multiply....
40000×30000=
= 1200000000
Here's your third part...
You need to divide 31 by 117
31÷117=
=0.2650%
Answer:
84 units2
Step-by-step explanation:
First, you multiply 24 *7 = 168
Second, you divide 168 / 2 = 84
Lastly, have a great day!
Answer:
Step 3, because the solution should also include all the values for x between the two given values
Step-by-step explanation:
step 1
we have


step 2
The graph in the given problem
step 3
Identify the solution when 
so

using a graphing tool
The solution is the interval -----> [3,5]
see the attached figure
All real numbers greater than or equal to 3 and less than or equal to 5
therefore
The first step in which the student made an error is step 3
Answer:
n = 19.89694
Step-by-step explanation:
You can work the problem using decimal numbers. There is no need to convert everything to integers. Trying to do so just gets you in trouble.
Subtract 2.2 from both sides:
-1.398 -2.200 = n/-5.53
-3.598 = n/-5.53
Now, multiply both sides by -5.53:
(-5.53)(-3.598) = n = 19.89694

The one rule that cannot be violated in algebra is that <em>you must do the same thing to both sides of the equation</em>.

Your "solution" so far has a couple of errors. The first is that you have apparently multiplied all of the numbers by 1000. Unfortunately, when you multiply a denominator by 1000, it is the same as dividing by 1000. So, you have multiplied the left side by 1000, multiplied one term on the right by 1000 and divided another term on the right by 1000. This turns the equation into something different than what you started with, and will give a wrong answer.
The second error is that you have subtracted 2200 only from the right side. This, too, will turn the equation into something different than what you started with, and will give a wrong answer.
