Answer:
a.
= 
b. 
Step-by-step explanation:
a) When <em>n </em>is even, then it is divisible by 2. Because of this, you can write:
b) When <em>n </em>is odd, then <em>n - 1 </em> is even. This would make it divisible by 2, and there would be a remainder of 1, so we can write:
× 
× 
Y=9x because if you divided y by x all the numbers will equal to 9 which is proportional
97.2% on the final.
Find the total amount of points needed to get a 93%. 150+150+150+250 = 700 total points. 700*.93 = 651 total points needed to get 93%. find the points received from the other quizzes and subtract the sum from 651 to find how many points need to be scored on the final.
150*.88=132 (test 1)
150*.94=141 (test 2)
150*.90=135 (test 3)
132+141+135= 408
651-408 = 243 points to score on the final exam.
243/250 =.972 or 97.2%
3:1 because she makes 3 times more baskets than John.
If a bowl of fruit contains 8 lemons and 6 oranges, then the ratio of oranges to lemons is eight to six or 8:6 which then can be reduced by to 4:3.
You reduce it by a common factor they share such as 2, because 2 x 4 = 8 and 2 x 3 = 6.
Hope that is the answer you seek.
