Question

simplify.
5.5v - 3.9v

Explanation:

Step1: Factor out the common variable \( v \)

We can use the distributive property in reverse, which states that \( ax - bx=(a - b)x \). Here, \( x = v \), \( a = 5.5 \), and \( b = 3.9 \). So, \( 5.5v-3.9v=(5.5 - 3.9)v \).

Step2: Subtract the coefficients

Calculate \( 5.5-3.9 \). \( 5.5-3.9 = 1.6 \). So, \( (5.5 - 3.9)v=1.6v \).

Answer:

\( 1.6v \)
