Answer:7 5/12
Step-by-step explanation:
12 2/3 times 4 on both sides is become 8/12
3 1/4 times 3 on both sides is 3/12
12 8/12 minus 3 3/12 equals to 7 5/12
Answer:
The each have to place 2 subscriptions
Step-by-step explanation:
Adriana
E (earnings) = 6 + 2*x where x is the number of subscriptions
Sophie
E (earnings) = 4 + 3x
For them to earn the same amount, their right sides must be equated.
4 + 3x = 6 + 2x Subtract 2x from both sides
4 + 3x - 2x = 6+ 2x - 2x Combine
4 + x = 6 Subtract 4 from both sides
4 - 4 + x = 6 - 4
x = 2
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 ;
