Let's say you have 10 and 15
You can divide both of them by 5
10/5=2
15/5=3
The greatest common factor is 5, because it is the highest number you can divide both numbers by, I hope this helps
(-8x)<span> ÷ (-4)=0
First you have to divide both sides by -4:
2x</span><span> ÷ 1=0
Now divide both sides by 1 so that the left side can be eliminated:
2x=0
</span>Now divide both sides by 2 so that the left side only has x:
x=0
It grows 2.5 inches in a month,
and 1 inch=2.54cm
then to know how many cm the plant grows in a month, we multiply
2.5*2.54=6.35cm
Total number of marbles = 5 + 8 + 7 = 20
Total number of non-red marbles = 5 + 7 = 12
P(not red) = 12/20 = 3/5
-
Answer: 3/5
