Question

deshaun has 28 new magazines to read. let m be the number of magazines he would have left to read after reading r of them. write an equation relating m to r. then use this equation to find the number of magazines he would have left to read after reading 22 of them. equation: number left to read after reading 22 of them: \boxed{} magazines

Explanation:

Step1: Define the relationship

The total number of magazines is 28. The number left \( M \) is the total minus the number read \( R \). So the equation is \( M = 28 - R \).

Step2: Substitute \( R = 22 \)

Substitute \( R = 22 \) into the equation \( M = 28 - R \). So \( M = 28 - 22 \).

Step3: Calculate the result

\( 28 - 22 = 6 \).

Answer:

Equation: \( M = 28 - R \)
Number left to read after reading 22 of them: 6 magazines
