To solve the inequality \( 25m - 7 \leq 17 \), we can break it down into two easy steps. I'll explain why I do each step!
Step 1: Add 7 to both sides
Why I can do this: When you add (or take away) the same number from both sides of an inequality, it doesn't change the story; the inequality sign stays the same.
So, I add 7 to both sides like this:
\[ 25m - 7 + 7 \leq 17 + 7 \]
Now, let’s simplify it! The left side becomes:
\[ 25m \quad (\text{because } -7 + 7 = 0) \]
And the right side becomes:
\[ 17 + 7 = 24 \]
So now we have:
\[ 25m \leq 24 \]
Step 2: Divide both sides by 25
Why I can do this: When we divide (or multiply) both sides of an inequality by a positive number, it also doesn’t change the direction of the inequality.
Now I divide both sides by 25:
\[ \frac{25m}{25} \leq \frac{24}{25} \]
This simplifies to:
\[ m \leq \frac{24}{25} \]
Conclusion
So, the solution to the inequality \( 25m - 7 \leq 17 \) is:
\[ m \leq \frac{24}{25} \]
And that’s how we solve the inequality step by step!
