Question

starting at zero, which expression represents the number line shown below? a ( 3.75 + -3 ) b ( -3 + 3.75 ) c ( -3 - 3.75 ) d ( 3.75 - -3 )

Explanation:

Step1: Analyze number line movement

Start at 0, first move left 3 units to $-3$, then move right 3.75 units to $0.75$. This is equivalent to adding 3.75 to -3.

Step2: Match to expression

The sequence of operations is $-3 + 3.75$. Verify the result: $-3 + 3.75 = 0.75$, which matches the final position on the number line.

Answer:

B. -3 + 3.75
