9 + 7 = 16 9 - 7 = 2
No because 9+7 = 16 which is a rational number
The sum of 16+2=18, and half of that is 9, so the question would be 16 minus what equals 9. So, the answer would be 7.

Set up the prolem as x + 9 = 16 (with x representing the unknown number) and solve: x + 9 = 16 (then subtract 9 from each side of the equation to solve for x) x = 7 Prove the answer by substiting 7 for x: x + 9 = 16 7 + 9 = 16 16 = 16
25 is a square number, and the sum of 9 and 16 is 25. 9 and 16 are also square numbers.
9 + 7 = 16 9 - 7 = 2
No because 9+7 = 16 which is a rational number

Yes 16+9=25
Find the answer by substituting number into the equationX + X2 = 90and you will find thatX = 9
The number is 9.
25 is the sum of 9 and 16. (52 = 32 + 42)
