Final answer:
To determine the weight of the bald eagle, an equation is set up based on the relationship provided and solved to find that a bald eagle weighs 12 pounds, which does not match the provided options.
Step-by-step explanation:
The student's question involves solving for the weight of a bald eagle given that an ostrich weighs 225 pounds, which is 15 pounds less than twenty times the weight of the bald eagle. First, we can represent the weight of the bald eagle as a variable, let's use 'b'. According to the problem, 20 times the weight of the bald eagle minus 15 pounds equals the weight of the ostrich, which can be formulated as the equation 20b - 15 = 225.
To find the value of 'b', we need to solve for it by first adding 15 to both sides of the equation, resulting in 20b = 240. Next, divide both sides of the equation by 20 to isolate 'b', giving us b = 240/20. This simplifies to b = 12. Therefore, the weight of the bald eagle is 12 pounds, which does not match any of the options provided (A. 240 pounds, B. 250 pounds, C. 260 pounds, D. 270 pounds) as those options are unrealistic for the weight of a bald eagle, considering that Golden Eagles, which are among the largest raptors, typically weigh between 8 and 12 pounds.
