Nine times a number decreased by four can be expressed mathematically as ( 9x - 4 ), where ( x ) represents the unknown number. This expression indicates that you first multiply the number by nine and then subtract four from the result.
The inequality for a number ( x ) that is decreased by two being at most four can be expressed as ( x - 2 \leq 4 ). Conversely, if the number decreased by two is at least nine, it can be represented as ( x - 2 \geq 9 ). Therefore, the combined inequalities are ( x - 2 \leq 4 ) or ( x - 2 \geq 9 ).
The algebraic expression for 7 decreased by 4 times a number can be written as ( 7 - 4x ), where ( x ) represents the number. This expression captures the operation of subtracting four times the variable from seven.
48-n=4n-7
As the subtraction is done first, it needs to be in brackets; thus eighteen decreased by four then times three is: (18 - 4) × 3
n (number) minus four ----->n-4
Eleven
The inequality for a number ( x ) that is decreased by two being at most four can be expressed as ( x - 2 \leq 4 ). Conversely, if the number decreased by two is at least nine, it can be represented as ( x - 2 \geq 9 ). Therefore, the combined inequalities are ( x - 2 \leq 4 ) or ( x - 2 \geq 9 ).
The minimum value is above the maximum value. No answer exists.

How do you write half a number decreased by 8 is equal to the sum of the number and 14
The relevant inequality is 2n - 9 >= 24
the equation of that would be 4x-5 if that's what your looking for
48-n=4n-7
=34 times 9 = 306=
X = number 48 - X = 4X - 7
