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:
multiply: Length x Width x Height
Step-by-step explanation:
7/1 would be your answer. :)
Answer:
x is horizontal, at the bottom(left to right), and y is vertical, going up and down
Step-by-step explanation:
see above
The most likely answer would be "The boy who wore a green coat carried his sister home."
"who wore a green coat" would be the dependent adjectival clause which describes the boy.
It can also be the other way around.
"The boy who carried his sister home was wearing a green coat."
In this sentence, "who carried his sister home" would be the dependent adjectival clause which describes the boy.
On both examples given, the relative pronoun used would be "who".
