lesson 6-3 · extra practice
on sunday, jax biked 21.92 miles. this is 4.5 fewer miles than the number of miles he biked on saturday. let b represent the number of miles jax biked on saturday. write a subtraction equation that could be used to find the number of miles jax biked on saturday. use 21.92, 4.5, and b.
□ - □ = □

Explanation:

Step1: Define the relationship

Let \( b \) be miles on Saturday. Sunday's miles (\( 21.92 \)) are \( 4.5 \) less than Saturday's, so \( b - 4.5 = 21.92 \).

Step2: Identify the equation parts

The subtraction equation uses \( b \) (Saturday), \( 4.5 \) (difference), and \( 21.92 \) (Sunday). So the equation is \( \boldsymbol{b - 4.5 = 21.92} \).

Answer:

\( b - 4.5 = 21.92 \) (filling the boxes: \( b \), \( 4.5 \), \( 21.92 \))
