The answer should be 390=60s, assuming s is the number of shelves he would need.
By the way, if you want the answer using this formula:
390=60s
390/60=s
6.5=s
s=6.5
Answer:
7/18
Step-by-step explanation:
21 out of 54 = 21/54 = 7/18
Only 2 times. After that, there's only enough room in there for 21 more.
These facts all come about as a result of DIVISION. Divide 79 by 29 and you'll see.
7 - (c + 18) > 0
-1 (c + [11])
~Now multiply each of the sides by -1~
c + 11 < 0
~Then , subtract 11 from each of the sides that you're working with~
c < -11
~Lastly, "c" becomes a negative~
-c - 11.0 > 0
Therefore your answer would have to be:
c < -11
