I don't understand your question.
Answer:
Y=4
Step-by-step explanation:Solve for yy in (y=4)(y=4).
y=4y=4
2 Substitute y=4y=4 into 1-1/2=2
2
No Solution
Answer: 0.01
Step-by-step explanation:
0.0082 / 0.82 = 0.01
0.82 × 0.01 = 0.0082
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
