meriva

Answer:

B. -4.8 is located below 4.8 . TRUE

Step-by-step explanation:

The vertical line is called the Y - AXIS.

Here also, the integers are expressed as same as the horizontal axis.

.... -5, -4, -3, -2, -1 , 0 , 1 2,3 4,5 ....

In vertical line, If we move above 0, the value INCREASES.

If we move Below 0, the value DECREASES.

Now, consider the given cases:

A. -2.5 is located below -3.5 .

Here, as -3 lies Below -2.

So, -2 > -3 ⇒ -2.5 > -3.5

So, -2.5 is located ABOVE 3.5.

B. -4.8 is located below 4.8 .

Here, as -4 lies Below 4.

So, 4 > -4 ⇒ 4.8 > -4.8

So, -4.8 is located BELOW 4.8.

C. 3.25 is located above 3.75 .

Here, 3.75 > 3.25

⇒ 3.75 is located ABOVE 3.25.

D. -0.5 is located below -1.5 .

Here, as -1.5 lies Below 0.5.

So, -0.5 > -1.5

⇒ -0.5 is located ABOVE -1.5.

E. 0 is located below -0.87 .

Here, as -0.87 lies Below 0.

So,0 > -0.87

⇒ 0 is located ABOVE-0.87.

Explain how to model the division of –24 by –4 on a number line.

lianna [129]

Answer:

Here's one way to do it.

Step-by-step explanation:

-24 ÷ (-4)

-24 is the final number on the number line

-4 means you count by 4s on the number line moving backwards.

Start at 0 facing forward.
Move backwards in steps of four units from 0 to -24.
Count the number of steps you took (six).

Answer: +6 (The sign is + because you are still facing forward).
