An open circle means any number except the one in the circle. Here the number in the circle is 3. The arrows go to both sides. This means every number except 3. The answer is c. Which states that every number is included except 3. Basically meaning x is never equal to 3.
Answer:
13 and 32
Step-by-step explanation:
let one number be x
Then the other number is x + 19 , then
x + x + 19 = 45
2x + 19 = 45 ( subtract 19 from both sides )
2x = 26 ( divide both sides by 2 )
x = 13
The 2 numbers are 13 and 13 + 19 = 32
The sum to 6+7 is 13 and the answer to 8+4 is 12 and the sum to 2+9 is 11
