The sum of three numbers is 18. If every number is a prime number, what are the three numbers?
sleet_krkn [62]
The three numbers are 2, 5, and 11.

The sum of 3 numbers is 18.        2 + 5 + 11 = 18

Since the problem states that every number is a prime number, then the number must be a natural number greater than 1 that has no positive divisors other than 1 and itself.

2 / 1 = 2  OR  2 / 2 = 1  These numbers are prime numbers because their divisors
5 / 1 = 5  OR  5 / 5 = 1            are 1 and itself.
11/1 = 11 OR 11/11 = 1

Sandra saves 12% of her salary for retirement. This year her salary was $3,000 more than in the previous year, and she saved $4,
slava [35]
So since we know she saved 12% in the previous year so you would make a graph and then draw 100 squares now since 12 dosen't go into 100 evenly you would multiply 12 until you get 96% (which is multiplying 12 by 8) then her salary would be $4,200 dollars multiplied by 8 which is 33,600 dollars then to get your 4 more percent you would divide 12 by 3 which is 4 and you would also divide 4,200 by 3 which is 1,400 and add that to 33,600 dollars and her salary would be 35,000 dollars in the previous year her current year salary would be 38,000 dollars.
