F=8p
63=f+p
Use substitution. f is already isolated, so sub the equation 8p into 63=f+p for f.
63=8p+p
63=9p
Divide both sides by 9 to get
p=7
You now have the weight of the parakeet. Multiply 7 by 8 to get the weight of the fish.
f=56
The answer is 5.7 hope that helps
1. no solution
2. infinite
3. ( x , y ) = ( 0 , b ) (one solution)
4. infinite
Answer:
x>7
Step-by-step explanation:
First, you take away 6 from both sides, which gives you 4x>-x+35. Then you add x to both sides, which makes it 5x>35. Divide both sides by 5, and you get x>7
$4.50 because 3 were free wich means 9 cost money 9*0.50=4.5
