A number line can help to show that 12 - (-5) equals 17 because it visually represents the concept of adding and subtracting numbers.
On the number line, Miki can start at the number 12 and move 5 units in the negative direction to reach the number 7. This represents the subtraction of -5 from 12, resulting in the value of 7.
Alternatively, Miki can start at an arbitrary point on the number line and move 12 units in the positive direction to reach the number 17. This represents the addition of 12 to the starting point, resulting in the value of 17.
In both scenarios, the number line shows the process of subtracting or adding a specific number, which helps to demonstrate why 12 - (-5) is equal to 17.
Miki is trying to help her younger brother understand why is equal to 17. She draws a
number line to help. Explain how a number line could help to show that is equal to 17.
(1 point)
12 − (−5)
12 − (−5)
Starting at 12 on the number line, you must move 5 units in the
negative direction to get to 7.
Starting at on a number line, you must move 12 units in the
positive direction to get to 17.
−5
Starting at 12 on the number line, you must move 17 units in the
negative direction to get to −5 .
Starting at on the number line, you must move 17 units in
the positive direction to get to 12.
