Answer:
32 minutes
Step-by-step explanation:
This can be calculated with some good old division and multiplication:
Step 1 - Divide the word count by the number of words every 2 minutes:
2000 ÷ 125 = 16
Step 2 - Multiply the 16 by the 2 minutes:
16 * 2 = 32
The 16 is the number of words it would take and multiply the 16 by 2 will tell us the number of minutes it would take for the whole document to be written.
So it would take him 32 minutes.
Hope this helps!
-64/3 divide -64 by 3
-21.33333333333333333
or
-21 1/3
Often with regrouping of 2 numbers then counting them once all together
After a first glance you can see that 3x^2 - 75 is not a difference of squares in the current form, because for one 3 and 75 are not squares.
So we'll have to see if we can factor something out of both of them. The only number it can be is 3, because the only number besides 3 that goes into 3 is 1.
So is there any number that can multiply by 3 to equal 75?
If you said 25 then you are correct. :p
So then our problem would look like this:
3(x^2 - 25)
Now we have a difference of squares!
Remember a difference of squares can be factored like this!
(a^2 - b^2) = (a - b)(a + b)
3(x - 5)(x + 5)
Is our answer!
If I knew the answer I would helped u b,
ut I'm only in 7th grade but I will try
