Answer:
7 apples left
Step-by-step explanation:
So he has 15 apples. IF he gives aways 8, he only has 15-8= 7 apples left
Answer:
y 》 2
y > -x + 3
Step-by-step explanation:
Equation of the bold line:
m = (-3/3) = -1
y = -x + 3
Shaded region is below y=2 (dotted)
So, it's defined by y < 2
Also, it's below the bold line
y 《 - x + 3
Everything outside these is not shaded:
y 》2
and y > -x + 3
I think it is y=-.25
7*3 - 4y = 20
21 - 4y = 20
subtract 21 from each side
- 4y = - 1
divide each side by - 4
y= -.25
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
1/10 currant
2/5 is cherry × 2 to get it out of 10
so 4/10 (cherry) + 1/10 (currant) = 5/10 so 5 raisins
