The Number Line with Signed Numbers: Place on the axis

Examples with solutions for The Number Line with Signed Numbers: Place on the axis

A negative number is greater than (-6).

Express the number in terms of b.

First, we'll mark on the axis the expression $b < 0$

Then we'll mark on the axis the expression $b > -6$

We'll mark in orange the segment representing the requested expression:

$0 > b > -6$

$0 > b > -6$

Express a number that is greater than 3 but less than 7 in terms of a.

First, we'll mark on the axis the expression $a > 3$

Then we'll mark on the axis the expression $a < 7$

We'll mark in orange the segment representing the requested expression:

$3 < a < 7$

$3 < a < 7$

The expression c is a negative number greater than (-9) and less than (-1) . Write it in mathematical language and mark it on the number axis.

First, we'll mark on the number line the expression $C < 0$

Then we'll mark $C > -9$

And finally $C < -1$

Now we can see that the section marked in orange overlaps with the expressions we marked:

The numbers that create the overlapping section start from -9 to -1 and represent the requested expression:

$-9 < c < -1$

$-9 < c < -1$

a is a positive number less than 5.

Where is a on the number line?

First, let's mark on the axis the expression $a < 5$

Now let's mark on the axis the expression

$a > 0$

Let's mark in orange the overlapping segment that represents the requested expression:

$0 < a < 5$

$0 < a < 5$
