Question

HELP! :3

Answer 1

Ted practices two types of swimming styles for a total of 50 minutes every day. He spends 20 minutes more practicing the breast stroke than the butterfly stroke.

Part A: Write a pair of linear equations to show the relationship between the number of minutes Ted practices the butterfly stroke every day (x) and the number of minutes he practices the breast stroke every day (y). (5 points)

Part B: How much time does Ted spend on practicing the breast stroke every day? (3 points)

Part C: Is it possible for Ted to have spent 45 minutes practicing the butterfly stroke every day? Explain your reasoning. (2 points)

Answer 3

I think I did Part A Correctly:

{x + 20 = y
{x + y = 50

Answer 4

Yes, DG, your system of linear equations is perfect.
Part B asks you to find the number of min. that our swimmer spends daily practicing the breast stroke. In other words, we're to find the value of y. One of the quickest ways in which to accomplish this is to eliminate x. (You and I eliminated x in the previous problem we worked on.)

Thanks, I got the question. Thanks.
