36 - x
1.6667
x-2
Lets assume the number = x. Also the expression means a function of x, f(x) which is often simply called y.So to show less than a number (x) the expression would read:f(x) = x-5 or y = x-5 Hope this helps.
The algebraic expression for "7 less than x" is x - 7. This expression represents the value of x decreased by 7. It can also be written as -7 + x, which means the same thing but follows the traditional order of operations in algebra.
x/2 - 9
X + 9 < 5
That expression is x-6.
let the no. be 'x' therefore, the expression of 5 less than a no. is, x-5
36 - x
It is: x-5
1.6667
x - 8
The discriminant of this quadratic expression is less than zero therefore it cannot be factored.
x - 11
x - 10
It is: x-5
