Question

74+783+7393783993+83938

Answer 1

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

`39>156g`

By substituting g=1|/4, we get

`39>156*(1)/(4)`

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".
