Answer:
Explanation:
The statement is expressed as 
y
∝
1
x
 
inverse means 
1
variable
 
To convert to an equation introduce k, the constant of variation.
y
=
k
×
1
x
 
⇒
y
=
k
x
 
To find k use the given condition that y = 8 when x = 4
8
=
k
4
⇒
k
=
4

Answer:
The dog weighs 16 pounds, while the cat weighs 8 pounds
Step-by-step explanation:
Let's call the weight of the dog d, and the weight of the cat c.
d+c=24
d=2c
Substitute the second equation into the first:
(2c)+c=24
3c=24
c=8
d=24-8=16
Hope this helps!
