Answer:
9x-7
Step-by-step explanation:
AB =3x-2
BC= 6x-5
AC=AB+AC
AC=(3X-2)+(6X-5)
AC=3X-2+6X-5
AC=3X+6X-2-5
AC=9X-7
Remove parentheses.
8.5+(2s+0.5)
Remove unnecessary parentheses.

If you have no calculator, pretend like the decimals aren’t there then add them back depending on how many places you have after the decimal. for example: 2.5 times 2.5, if you pretend there are no decimals, you get 625, then you have to add the decimals back. since you have 1 digit after each decimal in each number, you add 1+1=2 to get the number of places you have to add back. so you get 6.25
Answer:
900,000 books.
Step-by-step explanation:
The volume of the container = 24 * 9 * 8
= 1728 m^3
The volume of each book = 20*16*6 = 1920 cm^3
There are 100*100*100 = 1,000,000 cm^3 in 1 m^3.
So the number of books the container can hold
= (1728 * 1000000) / 1920
= 900,000.
