Question
A number line with arrows at both the ends ranges from negative 110 to negative 70 in increments of 1, but labeled in increments of 10. A closed circle is placed on negative 75, which is also labeled, and negative 105. A curved arrow is drawn leftward from negative 75 to negative 105.
Which word problem matches the model?

GPT 3.5
The correct explanation using the number line is:
Starting at 12 on the number line, you must move 17 units in the negative direction to get to negative 5.
Explanation: The number line shows the progression of numbers from left to right. Starting at 12, if you move 17 units in the negative direction, you will reach -5. This demonstrates the subtraction 12 - (-5) or 12 + 5, which equals 17.

Multiply −9⋅(−18)
GPT 3.5
To model and represent -9 * (-18), we can use the concept of repeated addition or grouping:
-9 * (-18) = (-9) + (-9) + (-9) + ... + (-9) (a total of 18 times)
Explanation: By repeatedly adding -9 a total of 18 times, we can represent the multiplication -9 * (-18).
-9 * (-18) = (-9) + (-9) + (-9) + ... + (-9) (a total of 18 times)
Explanation: By repeatedly adding -9 a total of 18 times, we can represent the multiplication -9 * (-18).

multiply the problem not represent by using a model
GPT 3.5
To multiply -9 * (-18), you can use the concept of multiplication with two negative numbers:
-9 * (-18) = 162
Explanation: When multiplying two negative numbers, the result is always positive. Therefore, -9 multiplied by -18 equals 162.
-9 * (-18) = 162
Explanation: When multiplying two negative numbers, the result is always positive. Therefore, -9 multiplied by -18 equals 162.

The correct model to represent -30 ÷ -6 is:
(−5) + (−5) + (−5) + (−5) + (−5) + (−5) = 6(−5) = −30
Explanation: By adding -5 a total of 6 times, we can represent the division -30 ÷ -6. This demonstrates that dividing -30 into groups of -6 results in 6 groups of -5, which equals -30.
(−5) + (−5) + (−5) + (−5) + (−5) + (−5) = 6(−5) = −30
Explanation: By adding -5 a total of 6 times, we can represent the division -30 ÷ -6. This demonstrates that dividing -30 into groups of -6 results in 6 groups of -5, which equals -30.

Explanation: By adding -6 a total of 6 times, we can represent the division -30 ÷ -6. This demonstrates that dividing -30 into groups of -6 results in 6 groups of -6, which equals -30.
(-6) + (-6) + (-6) + (-6) + (-6) + (-6) = 6(-6) = -30

Explanation: By adding -6 a total of 6 times, we can represent the division -30 ÷ -6. This demonstrates that dividing -30 into groups of -6 results in 6 groups of -6, which equals 36.
(-6) + (-6) + (-6) + (-6) + (-6) + (-6) = 36

Elaine used the subtraction algorithm to subtract −17−(−3). She got the answer −14, but she does not feel confident that she is correct. Connect the expression −17−(−3) to a two-color counter model. Explain how the two-color counter model can be used to confirm whether Elaine’s answer is correct.(2 points)
GPT 3.5
The expression -17 - (-3) can be connected to a two-color counter model as follows:
1) Start with 17 counters of one color to represent -17.
2) Subtract 3 counters of the other color to represent -(-3).
The resulting model will have 14 counters remaining in the original color, which confirms Elaine's answer of -14.
Explanation:
By using a two-color counter model, we can visually represent the subtraction problem -17 - (-3). We start with 17 counters to represent -17, and then we subtract 3 counters to represent -(-3). This action of removing counters of the other color represents the subtraction of a negative number. If we end up with 14 counters remaining in the original color, it confirms that Elaine's answer of -14 is correct.
1) Start with 17 counters of one color to represent -17.
