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

yarga [219]

Answer:

X = 18

Y = 18

Step-by-step explanation:

first make two equation like

x + y = 36

1180x + 125y = 23490

from equation one we have

y = 36- x

put in second equation

1180x + 125 (36-x) = 23490

1180x + 4500-125x = 23490

1055x = 23490-4500

x = 18990/1055

x = 18

put this x value in equation 1 to find y value

18+ y = 36

y = 36-18

y = 18
