Which of the following is not a way to represent the solution of the inequality 7 - 9x - (x + 12) less than or greater to 25?
1 answer:
<span>To answer the question above first we need toclarify what the inequality is actually saying:
7 - 9x - (x + 12) </= 25 (simplify)
-5 - 10x </= 25 (add 5 to both sides)
-10x </= 30 (divide by -10 to get x)
x >/= -3 (don't forget to flip the signs when you divide by a negative number)
So this says x is greater than or equal to -3, so which of these statements is not a way to represent that?
I'd say it's the second one. x is greater than not less than.</span>

Step-by-step explanation:
perimeter of a rectangle = 
= 138m^2= 2(2x + 6 ) + 52
= 4x + 12 + 52 = 138
= 4x + 64 = 138
= 4x = 138 - 64
= 4x = 74
= x = 74/4
= x = 18.5
