Answer:
11
Step-by-step explanation:
2.5 - 0.5x = -3
*Inverse operations
-3 - 2.5 = - 5.5
-0.5x = -5.5
-5.5 / -0.5 = 11
Answer: There are 9216 different ways.
Step-by-step explanation:
Since we have given that
Number of couples = 4
Number of people in couples = 8
Number of seats on each floor = 4
Number of ways to select a person from each to send him (or her) to the upper deck would be
Number of ways to select a person to send them to the bottom floor would be
Number of ways to select a person to send them to the upper floor would be :
So, the total number of different ways would be :
Hence, there are 9216 different ways.
