A \(x\leq 7\)
B \(x\geq 7\)
C (x<7)
D (x>7)
Explanation opens after your attempt
Correct Answer
A. \(x\leq 7\)
Step 1
Concept
Not more than means \(\leq\), so \(2x+5\leq 19\) gives \(x\leq 7\). In word problems, first convert the sentence into an inequality.
Step 2
Why this answer is correct
The correct answer is A. \(x\leq 7\). Not more than means \(\leq\), so \(2x+5\leq 19\) gives \(x\leq 7\). In word problems, first convert the sentence into an inequality.
Step 3
Exam Tip
अधिक नहीं है का अर्थ \(\leq\) होता है, इसलिए \(2x+5\leq 19\) से \(x\leq 7\) मिलता है। शब्द प्रश्नों में वाक्य को पहले असमानता में बदलें।
