Lets start with question 2. In this case, we have

By substituting g=1|/4, we get

which gives

$\begin{gathered} 39>(156)/(4) \\ 39>39 \end{gathered}$

But this result is incorrect because 39 is equal to 39 not greater than 39. So, the answer is false.

Question 3.

In this case, we have the following expression:

$(f)/(4)\le3$

By substituting f = 12, we have

$(12)/(4)\le3$

which gives

$3\le3$

This result is correct because the symbol

$\le$

means "equal or less than". Then, our last result means 3 equal or greater than 3. So, the answer is true because 3 is equal to 3.

Question 4.

In this case, the expression is

$121-98\ge r$

By substituting r=23, we get

$121-98\ge23$

On the left hand side, we have 121-98=23, then, our last result is equal to

$23\ge23$

and this is true, because the symbol

$\ge$

means "greater or equal to".
