Question

here is a number line,
20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40
a. write an equation that the number line represents.

b. how does your equation match the number line?
explain your reasoning.

Explanation:

Part (a)

Step1: Identify start and end points

The number line starts at 35 and moves left to 27. The distance between 35 and 27 is \( 35 - 27 = 8 \), so we're subtracting 8 from 35.

Step2: Write the equation

The equation representing the number line is \( 35 - 8 = 27 \).

The equation \( 35 - 8 = 27 \) matches the number line because the arrow starts at 35 (the minuend), moves 8 units to the left (subtracting 8), and ends at 27 (the difference). This visually represents the subtraction operation in the equation.

Answer:

\( 35 - 8 = 27 \)

Part (b)
