Q: The sum of a number and 9 is 16. find the number?

Write your answer...

7

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

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.

-3.5

-3.5

Yes 16+9=25

Find the answer by substituting number into the equationX + X2 = 90and you will find thatX = 9

The number is 9.

16-5= 9

25 is the sum of 9 and 16. (52 = 32 + 42)

16

16

⅔ a number - 9 = 7 → ⅔ a number = 7 + 9 = 16 → the number is 16 × 3/2 = 24.

to find the root-sum square of n numbers you square each number, add them, then take square root of sum For exanple root sum square of 2,3, and 4 is square root of (4+9+16) = sqrt(29) = 5.39

it is 16...dumbie

the answer is -9....

7 is the product of the sum 16-9

25

The number is 9, because 9 + 2/3(9) is 15, so 9 + 6 = 15 because 2/3 of 9 is 6.

the sum is the answer to an addition problem e.g.4+5=9 9 is the sum
