*SUPER EASY* asks people for the answer
uhm I'd say a and maybe d
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
Solving for h means we write the equation in such a way that h is isolated from other variables. It is done as follows:
(P = mgh) 1/mg
P/mg = mgh/mg
h = P/mg
Therefore, the correct answer from the choices listed above is option C, h = p/mg.
Hope this answers the question. Have a nice day.
Rotating the entire polygon should have no effect on its internal angles. I hope my answer has come to your help. God bless and have a nice day ahead! Feel free to ask more questions here in Brainly.
