As a number sentence it is:
X - 9
32 minus the product of 9 and a number is 140 the answer is 12. 32-9x=140 9x=108 x=12
x/2 - 9 = 14 x/2 = 23 x = 23 x 2 x = 46
X = 240
(x + 2)(x - 9)
9(x-5)
The term is: 9-x
Minus. You are multiplying a negative number a positive number of times. -3(2) -9
(.50)(x)=x-7
32 minus the product of 9 and a number is 140 the answer is 12. 32-9x=140 9x=108 x=12
x/2 - 9 = 14 x/2 = 23 x = 23 x 2 x = 46
X = 240
It looks like it is just minus nine each time. The first number is 9 x 10, then 9 x 9, then 9 x 8.
The only number in that whole string of words whose value you don't already know, and can change from one minute to the next, is 'x'.
(x + 2)(x - 9)
Let the number be x and so if 32 -9x = 140 then the value of x is -12 Check: 32 -9*(-12) = 140
I believe it is prime as you have written it. change the end to + 81 and it factors as (2x - 1)(x-9)(x+9)
9(x-5)
