Answer 1

Question: The weights of two beluga whales and three orca whales totals 36,000 pounds. The weights of one of the belugas and one of the orcas add up to 13,000 pounds. Using this information only, how much do the belugas weigh? How much do the orcas weigh?

Part 1: Write a system of equations for this problem and solve it by graphing. (You can write 36,000 and 13,000 as 36 and 13 respectively as long as you remember to put the thousand back on in your answer.) You can download a graphing program (information is provided in the course information area) to create your graph or just draw them on paper. Be sure to indicate the point of intersection on the graph by writing your answer as an ordered pair.

Part 2: Using the same system of equations, solve it by substitution. Be sure to show all work in this process; a final answer is not enough to earn credit. Answer the question in complete sentences.

Part 3: Solve the same system of equations by the addition method. Again, be sure to show all work and indicate your answers in complete sentences.

Answer 3

nvm

Answer 4

B = weight of beluga whale
O = weight of orca

"The weights of two beluga whales and three orca whales totals 36,000 pounds."
2B + 3O = 36000

"The weights of one of the belugas and one of the orcas add up to 13,000 pounds."
B + O = 13000

So, now you have a system of equations to solve.
2B + 3O = 36000
B + O = 13000

Answer 5

For substitution, I recommend rearranging the second equation...
