141 (The original number) ;1 + 4 + 1 = 6 (Add each individual digit together) ;6 is divisible by 3 ;Then 141 is divisible by 3 ;141 isn't a prime number ;In the same way, 171 is divisible by 9 ; then, 171 isn't a prime number ;
161 = 7 x 23; 161 is divisible by 7 ; then, 161 isn't a prime number ;
Test whether 171 is divisible by 2, 3 , 5 , 7 , 11 , 13 ( <span>an algorithm that tests each incremental </span>m<span> against all known primes < </span> division ) ;
but, 171 isn't divisibile by 2,3,5,7,11,13 ;
Finally, 171 is a prime number ;
Answer:
x=3
Step-by-step explanation:
First, combine like terms on the left side
4x-5x+9=5x-9
-x+9=5x-9
Subtract 9 on both sides
-x=5x-18
Subtract 5x on both sides
-6x= -18
Divide by -6 on both sides
x=3
Hope this helps! :)
Answer:
72
Step-by-step explanation:
Area = base * height
Area = 9 * 8 = 72
Answer: There are 90 different schedules are possible for Molly Kay.
Step-by-step explanation:
Since we have given that
Three time scheduled at 8:00, 10:00, 11:00.
Number of courses offer at 8:00 = 5
Number of courses offer at 10:00 = 9
Number of courses offer at 11:00 = 2
So, the number of different schedules are possible for Molly Kay is given by

Hence, there are 90 different schedules are possible for Molly Kay.
either a rectangle or circle will be made. If you cut it horizontially you will get a circle. Vertically and you will have a rectangle
