Answer: 36
Step-by-step explanation:
Given: Sapphire shelves 12 books at a time, whereas Abe shelves 18 at a time.
If they end up shelving the same number of books, what is the smallest number of books each could have shelved = LCM (12,18)
12 = 2 x 2 x 3
18 = 2 x 3 x 3
LCM (12, 18) = 2 x 2 x 3 x 3 = 36
Hence, the smallest number of books each could have shelved = 36
Answer:
C) -8 + 3a + 10 -a = 2a + 2
Step-by-step explanation:
The did not combine like terms correctly.
Step SHOULD'VE went like this:
20-26=-6 & -34+60=26
-6+9=3
3=26
Divide!
3÷3=0 ⇒26÷3=8.6666.....
or (rounded)
the answer would be 8.7
