Which expression is represented by the model below?
The picture show an arrow pointing above the number line from -7 to -2 and the arrow under the first arrow pointing from 0 to -7.
A. -7 + (-5)
B. -7 + (-2) **
C. -7 + 0
D. -7 + 5 **
I can't decide between B or D so could someone help me?
I'm so sorry for posting what I posted just please don't come to my house and kill me by the way it may say I live in Ohio, but I actually live in Alabama
Actually it will be pretty hard to visualize the picture so could anyone explain how I should answer this question instead?
nobody's gonna kill you bro XD
imma kill all of you
To determine which expression is represented by the model, we need to analyze the given information.
The arrow pointing above the number line from -7 to -2 represents a movement of 5 units to the right, which indicates addition.
The arrow below the first arrow, pointing from 0 to -7, represents a movement of 7 units to the left, which indicates subtraction.
Therefore, the expression represented by the model is -7 + (-2), as option B correctly shows a movement of 5 units to the right (addition) and 7 units to the left (subtraction).
Option D (-7 + 5) would represent a movement of 5 units to the right (addition), not a movement of 7 units to the left as shown in the model.
So the correct answer is option B, -7 + (-2).
