Which of the following statement is not true? a.3<5b.3≤5c.7≤7d.7≠7

Sagot :

To answer this question we have to understand what each of the signs represent.

The first one

[tex]<[/tex]

Means that a number to the right is lower than the one from the right. In this case

[tex]3<5[/tex]

Since 3 is lower than 5 this stament is true.

The second sign

[tex]\leq[/tex]

Means that the number on the right is lower OR equal to the one on the right. In this case

[tex]3\leq5[/tex]

Since 3 is lower than 5 this statment is true.

For the third stament we have the same sign than the second statement

In this case

[tex]7\leq7[/tex]

Since 7 is equal to 7, this statement is also true.

Finally , the sign

[tex]\ne[/tex]

Means that the number on the right is not equal to the one on the right

In this statement

[tex]7\ne7[/tex]

This says that 7 is not equal to 7, which is not true.

So the answer to the problem is d.
