Answer:
15 minutes
Step-by-step explanation:
Their rate together is 1/6 floor per minute.
Her rate alone is 1/10 floor per minute.
His rate is the difference of these:
1/6 - 1/10 = 5/30 -3/30 = 2/30 = 1/15 . . . . floor per minute
It would take Jacob 15 minutes to do it alone.
He would have started with a total of 2,278 packages of fruit chew packages.
First, you would multiply the 27 packages by the 85 cases wich is 2,275, then you would add the three leftover packages to the total making it 2,278.
Hope this was helpful. ;)
24a ^ 2-6a-9.
you should do in this case is to see the terms that are repeated in the expression.
WE have then that the terms are a and the multiples of 3.
Making a common factor we have:
24a ^ 2-6a-9.
3 (8a ^ 2-2a-3).
3 (a (8a-2) -3)
Answer:
The equivalent expression is:3 (a (8a-2) -3)
0.7 is just 7 tenths which is literally 7/10.
