12x > 9(2x-3)-15
distribute the 9
12x > 18x-27 -15
combine like terms on the right side
12x > 18x-42
subtract 18x from both sides
-6x > -42
divide both sides by -6
x = -42 / -6 = 7
x >7
yes
A rational number is a number which can be expressed in the form
where a and b are integers
now 2. 34 = 2 
= 
→ a rational number
Answer: 2.5 ft.
Step-by-step explanation: We know that the wall is 10ft and each poster is 1 1/4 ft, so subtract both posters from the wall, 10-2.5 = 7.5, then divide 7.5 by 3 since we need 3 lengths, and we get 2.5ft. So for x, it would be 2.5ft.
x=2.5

The right answer is Option C.
Step-by-step explanation:
Given word problem is;
Two more than three times a number is at least eight
Let,
n be the number.
Times a number = 3n
Two more means addition;
Two more than three times a number = 3n+2
At least eight means that it can either be 8 or more.
Therefore,
3n+2≥8 is the solution set.
The right answer is Option c.
