We are tasked to solve for the number of ways the 8 students be competing for the 1st, 2nd, 3rd, 4th voilin chair in the schools orchestra. The number of ways if can only be filled is though the formula used in number counting, that is
8x7x6x5
Therefore, there are 1680 ways
16,500
60 minutes in an hour / 12 minutes = 5
5 * 3,300 = 16,500
That statement would be best express by " x + 25 < 75 ". Since the statement says the sum of x and 25, thus, it will be x + 25. Then it also states that the sum is less than 75, so the best expression would be " < 75".
Answer:
1. none
Step-by-step explanation:
When you simplify the expression, you see that the statement is is false for any value of x.
