so together the amount of people who chose beef should be 4/12 since you must find the greatest commen factor. Then you should add 4/12 and 24 im thinking and you would get 24.3333 but if your looking for a mix number it would be 24 3333/1000
hope this helps!
So first create and define your variables:
Z = amount of zebra fish
N = amount of neon tetras
Now create your equations:
2z+2.15n=31.20
z+n=15
This is your system. There are multiple methods to use but in this problem I’ll use the substitution method by simplifying the bottom equation.
2z+2.15n=31.20
z=15-n
Now I’ll plug the bottom equation into the top one.
2(15-n)+2.15n=31.20
And just solve from here.
30-2n+2.15n=31.20
0.15n=1.20
n=8
So he bout 8 neon tetras, and 15-8= 7, so he bought 7 zebra fish
Answer:c
Just had it on apex
Step-by-step explanation:
Answer: 2/8
Step-by-step explanation:
The probability that the marbles are white or grey is 2/8 because since there is 2 marbles and the total is 8 so you have a probability of 25% to get white or gray
