Natalie is using colored tiles to help her add integers. She is using black tiles to represent positive numbers and white tiles to represent negative numbers. What number sentence is Natalie modeling with the tiles?
Responses
A 5 + (-4) = 15 + (-4) = 1
B 4 - (5) = -14 - (5) = -1
C 4 + (-5) = 94 + (-5) = 9
D 5 - (-4) = 9

Of course! What do you need help with in math?

(-1)(-16)(13) = 208

So the answer is A. 208

The two integers that are farthest apart on the number line are the ones that have the greatest distance between them.

The distance between -65 and 90 is 90 - (-65) = 155.

The distance between -42 and 65 is 65 - (-42) = 107.

The distance between 65 and 90 is 90 - 65 = 25.

The distance between -65 and -42 is -42 - (-65) = 23.

The greatest distance is between -65 and 90, so the answer is B. -65 and 90.

When we subtract a negative number, it is the same as adding its opposite. So,

-35 - (-12) = -35 + 12

= -23

Therefore, the answer is C. -23.

If he initially drew 3 balls and replaced 2, then he had 1 ball left in his hand.

When he drew out 4 more and replaced 1, he added 3 balls to his hand (he drew out 4 and replaced 1, which means he added 3 balls to his hand).

So, Oliver has 1 ball + 3 balls = 4 balls left in his hand.

Therefore, the answer is D. 4.
Answered by Bot
Yes, that's correct!

To find the distance from the basement floor to the roof, we need to find the difference between the elevation of the roof and the elevation of the basement floor.

Roof elevation = 36 ft

Basement floor elevation = -14 ft

Distance from basement floor to roof = roof elevation - basement floor elevation

= 36 - (-14)

= 36 + 14

= 50 ft

Therefore, the answer is E. 50 ft.

(15)(-13) = -195

Therefore, the answer is C. -195.

We cannot determine the number sentence without knowing the arrangement of the tiles. Please provide further information or a visual representation of the tiles.
Answered by Bot
That's alright. Can you please provide more details about the arrangement of the tiles, or the problem statement that goes with the tiles so that I can help you out?
Answered by Bot
Ok, based on the information given, we can conclude that:

- The black tiles represent positive numbers, and the white tiles represent negative numbers.
- There are 5 black tiles at the top, and 4 white tiles at the bottom.

This suggests that the number sentence that Natalie is modeling with the tiles is:

5 - 4 = 1

This means that if we have 5 positive numbers (represented by black tiles), and we take away 4 negative numbers (represented by white tiles), we are left with 1 positive number.

So, the answer is D. 5 - (-4) = 9

- 68 - 21 = - 89

Therefore, the answer is B. -89.
