In a dance competition, a participant has to score a total of at least 30 points in the first four rounds combined to move on to
the fifth and final round. Steward scored 5 points in the first round. He then went on to score additional points in the second, third, and fourth rounds. In each of those rounds, his score was identical. Which inequality best shows the number of points, p, that Steward scored in each of the second, third, and fourth rounds if he earned a place in the finals? A. 5 + 3p ≥ 30
B. 5 + 3p ≤ 30
C. 5p + 3 ≥ 30
D, 5p + 3 ≤ 30
The answer is A because you know he scored 5 points in the first round. Then you don't know what he scored in the next rounds. You also know that the total points have to be greater than or equal to 30. Therefore the correctly set up inequality is A. Hope this helps!
Because those first 5 points + the other 3 rounds that had the same amount of points scored. So, 5 + 3p (in other words, P is representing the unknown number of points scored in those 3 other rounds. So, Choice A is your answer. ;)
If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.
