As an algebraic expression it is: 2x-9
4p - 9 > 15
9-14
(92 x 2) - (9 x 2) = 162 - 18 = 144 The number is therefore 9.
110 over 9 as a mixed number = 122/9
number less than 100 that is divisible by 2 5 and 9 = 90
um, 9.
2n/6 - 9 or n/3 - 9
-9
2z+9
X = number. 4X + 9 = 2X - 15 ===========
The answer is 9.You solve it as:2x-9=x2x-x=9x=9
4x - 7 = 9
The way to write out the difference of 9 and a number is n-9.
2*abs(2-n) = 9
If you want to say "Nine is less than a number k," you would write 9<K. If you're asking for an equation, e.g. "Nine less than a number k is equal to that number divided by three," you would write k - 9.
If: 3y-7 = 2y+9 Then: 3y-2y = 9+7 So: y = 16
There is no selected number so it would be a variable. The answer is 2n-9 (n is the number which you choose)
