What two numbers have a sum of 17 and a difference of 1?
let the number be 'm' & 'n' m + n = 17 m - n = 1 Add 2m = 18 m - 18 / 2 = 9 Substituting 9 - n = 1 9 - 1 = n n = 8 So the two numbers are '8' & '9'.
What 2 integers have a sum of -9 and a difference of 5?
There seems to be a lot of questions like this and they are all solved the same way, The 2 integers are n and m, with n+m =-9 and n-m = 5. Add the 2 equations together and you get 2n=-4 so n=-2. Subtract one equation from the other and you get 2m=-14 so m=-7. Answer -2 and -7 Notice that there are 2 ways of getting the difference of 5. if you try m-n=5, you finish up with the same answer.
What is 9n equals 36?
If 9n = 36 then we divide both sides by 9 to discover what value n has If we divide 9n by 9 we get n If we divide 36 by 9 we get 4 so, if 9n = 36 the n = 4
9 is the difference of a number n and 7?
n - 7 = 9 n = 16
Rules in multiplying or deviding in scientific notation?
To multiply m x 10a by n x 10b: multiply the numbers (m x n) add the powers (a + b) (m x 10a) x (n x 10b) = mn x 10a+b To divide m x 10a by n x 10b: divide the numbers (m / n) subtract the powers (a - b) (m x 10a) / (n x 10b) = m/n x 10a-b

What is the difference of m and n?
the double of n is m. is the difference between m and n
The difference of 9 and a number n?
abs(9 - n) which is 9 - n if 9 ≥ n and n- 9 if 9 ≤ n

If 9n = 36 then we divide both sides by 9 to discover what value n has If we divide 9n by 9 we get n If we divide 36 by 9 we get 4 so, if 9n = 36 the n = 4
What is an integer with the sum of 16 and a quotient of -9?
25
What is 50mn divided by 35n?
1.4286
9 is the difference of a number n and 7?
n - 7 = 9 n = 16
Why is a negative divided by a negative a positive?
if we have two negative numbers, -n and -m and we divide them: (-n)/(-m) then we can rewrite the quotient as : (-1)*n/(-1)*m and... (-1)/(-1) * n/m we know that any number divided by itself is 1 by some rule: so = (-n)/(-m) = n/m which is positive
