Sean and his family rented a yacht for a day. Sean caught a baby shark and his dad caught a blue marlin. The weight of the baby shark was 12 times as great as the weight of the blue marlin. The combined weight of both fish was 273 pounds. How much did the baby shark weigh?

The baby shark weighed 252 pounds.

Step-by-step 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.
