Question

solve for r. 0.5(r + 2.75) = 3

Explanation:

Step1: Divide both sides by 0.5

To isolate the term with \( r \), we divide both sides of the equation \( 0.5(r + 2.75)=3 \) by \( 0.5 \). This gives us \( r + 2.75=\frac{3}{0.5} \). Calculating the right - hand side, \( \frac{3}{0.5}=6 \), so the equation becomes \( r + 2.75 = 6 \).

Step2: Subtract 2.75 from both sides

To solve for \( r \), we subtract \( 2.75 \) from both sides of the equation \( r + 2.75 = 6 \). Using the subtraction property of equality, we get \( r=6 - 2.75 \). Calculating the right - hand side, \( 6-2.75 = 3.25 \).

Answer:

\( r = 3.25 \)
