Answer:
The answer to your question is the big dog weighs 120 pounds
Step-by-step explanation:
Data
big dog = b
medium dog = m
small dog = s
Equations
b = 5s
m = 12 + s
s = 2/3 m
Process
1.- Substitute m in the last equation
s = 2/3(12 + s)
s = 24/3 + 2/3s
s - 2/3s = 8
1/3 s = 8
s = 8(3)
s = 24 pounds
2.- Substitute s in the first equation
b = 5(24)
b = 120 pounds
Answer: A. Ounces of water consumed compared with the number of same-size bottles drunk
Step-by-step explanation:
When a quantity changes uniformly with respect to the change of other quantity, then we say there is a constant rate of change.
Thus, if one quantity is directly proportional to the other quantity then there is constant rate of change.
A. Ounces of water consumed is directly proportional to the number of same-size bottles drunk. Hence there is a constant rate of change of ounces water with respect to the number of same-sized bottles.
Rest of other options do not have directly proportionality relation between the quantities.
