Question

Identify the subtraction equation that the given number line represents.

• A. $57–24=34$
• B. $57–22=34$
• C. $57–20=33$
• D. $57–23=34$

Answer 1

The correct option is D $57–23=34$

Detailed step-by-step solution:
On the number line, we can see two backward jumps from 57 to reach 34.
The first backward jump is from 57 to 37. Therefore, 20 is subtracted.
The second backward jump is from 37 to 34. Therefore, 3 is subtracted.

Here, the number to be subtracted from 57 is broken apart into 20 and 3.
20 + 3 = 23


Therefore, we can conclude that 57 – 23 = 34 is the equation that the number line represents.

Hence, Option C is correct.
