28. \( 1.2=m-2.5 \)

To solve the equation \( 1.2 = m - 2.5 \), you can isolate \( m \) by adding \( 2.5 \) to both sides. This gives you \( m = 1.2 + 2.5 \), which simplifies to \( m = 3.7 \). Now, when you're dealing with equations, remember to always check your final answer by substituting it back into the original equation. If both sides match, you're on the right track! In this case, plugging \( m = 3.7 \) back into the equation confirms that it holds true. Always check to avoid any sneaky mistakes!
