The names PNM and MPN are perfectly valid. The order of the letters doesn't matter. In fact, there are 6 ways to name this plane if we just use the 3 letters. If we include "plane Z", then there are 7 total ways to name the plane.
For some reason, your teacher wants P to be the third letter as s/he mentioned MNP and NMP. But again, the order doesn't matter.
Answer:
1 ≤ n
Step-by-step explanation:
7−3n ≤ n+3
+3n +3n
7 ≤ 4n+3
-3 -3
4 ≤ 4n
divide by 4 on each side
1 ≤ n
Im assuing the 0.6 is a percentage and not the number of passes then :
100% - 60% = 40%
Answer:
0 ways...
Step-by-step explanation:
First find one pair.
x and x + 1
2x + 1 = 100
2x = 99
x = 49.5
49.5 and 50.5
Since the only way is with decimals, there are 0 ways.
2/3 and 8/12 are proportional but 3/14 and 8/28 aren’t
