3. Solve and write as a mixed number
2n > 9 show your work
To solve for n, we need to isolate the variable n on one side of the inequality.
Given inequality: 2n > 9
We can isolate n by dividing both sides of the inequality by 2:
(2n)/2 > 9/2
Simplifying, we have:
n > 4.5
So, the solution to the inequality 2n > 9 is n > 4.5.
To write it as a mixed number, we can convert 4.5 to a mixed number:
4.5 = 4 + 0.5
Therefore, the solution can be written as:
n > 4 and n < 5
