1. We need to get rid of those pesky parentheses. We do this by distributing the 3.
2. We need to get "n" by itself, so we add 9 to both sides.
3. Add like terms.
4. Now, we need to get rid of the -9, so we divide both sides by -9. Remember that dividing by negative numbers changes the direction of the "greater than or equal to" symbol.
5. We divide, and the negatives cancel.
I wrote the answer both ways so that I could tell what the number line needed to look like.
Answer:
2.4 *103 = 247.2
1.5*103 = 154.5
3.6*106 = 381.6
3.9*106 = 413.4
3.6*109 = 392.4
3.9*109 = 425.1
Step-by-step explanation:
2.4 * 103
we firstly count decimal numbers
in the calculation
only 2.4 has a decimal and only one number after the point
so we keep it aside making
2.4 = 24 1 dp (decimal place)
back to the calculation
1 0 3
* 2 4
----------
4 1 2
2 0 6
-------------
2 4 7 2
-------------
don't forget we still have a dp !
so we place the point 1 step backward
2472 to 1dp =
247.2
with this we can solve orders
What's the question though I could gladly help
3 1/3 divided by 2 3/5 equals 1.28205128 (which would mean your answer for this one should be letter D.
<u>Answer:</u>
The answer is A
<u>Step-by-step explanation:</u>
The answer needs to be in slope-intercept form or y=mx+b because the amount of carpet being cleaned every minute is a constant decrease of 9 square feet.
So our b value (or how much carpet cleaned at 0 minutes) is 220
And our m value (or slope or how much carpet is being cleaned every minute) is 9
So if we plug the variables with the tangible numbers we get A(t) = -9x+220 or A(t) = 220-9x.
