Answer:
The baby shark weighed 252 pounds.
Explanation:
From the information given, you know that the weight of the baby shark plus the weight of the blue marlin is 273, which could be expressed as:
x+y=273, where:
x is the weight of the baby shark
y is the weight of the blue marlin
Also, you know that the weight of the baby shark was 12 times as great as the weight of the blue marlin, which could be expressed as:
x=12y
Now, you can replace x=12y in x+y=273 and solve for y:
12y+y=273
13y=273
y=273/13
y=21
Now, you can replace the value of y in x=12y to find the value of x:
x=12(21)
x=252
According to this, the answer is that the baby shark weighed 252 pounds.
