The answer is 120 because 5 factoral or 5! is the number of combinations that they will get off at different floors.
A prime number is a number which is only divisible by one and itself, no other number can be used to divide it without having a remainder.
From the set of number given above, the one that is not a prime number is 1057, this is because, 7 can be used to divide it without any number remaining.
1057/7 = 151.
Answer:
x=-2
Step-by-step explanation:
-9x+1=-x+17
Add 9x on both sides:
1=8x+17
Subtract 17 on both sides:
-16=8x
Divide both sides by 8:
-2=x
Check x=-2!
-9x+1=-x+17 with x=-2
-9(-2)+1=-(-2)+17
18+1=2+17
19=19
19=19 is a true equation so x=-2 is correct.
