Andre says that \(10x+6\) and \(5x+11\) are equivalent because they both equal 16 when \(x\) is 1. Do you agree with Andre? Explain your reasoning.
Select all expressions that can be subtracted from \(9x\) to result in the expression \(3x+5\).
Select all the statements that are true for any value of \(x\).
\(7x + (2x+7) = 9x+7\)
\(7x + (2x - 1) = 9x + 1\)
\(\frac12 x+(3 - \frac12 x)=3\)
\(5x - (8 - 6x) =\text-x-8\)
\(0.4x - (0.2x+8) =0.2x-8\)
\(6x - (2x -4)=4x+4\)
For each situation, would you describe it with \(x< 25\), \(x > 25\), \(x \leq 25\), or \(x \geq 25\)?
- The library is having a party for any student who read at least 25 books over the summer. Priya read \(x\) books and was invited to the party.
- Kiran read \(x\) books over the summer but was not invited to the party.
