w≥8.6
w greater than or equal to 8.6
w≥51.2
w greater than or equal to 51.2
w≥86
w greater than or equal to 86
w≥860
- To solve the inequality 10w+213≥299, you need to isolate the variable w.
- Start by subtracting 213 from both sides of the inequality: 10w+213-213 ≥299-213.
- Simplify the equation: 10w≥86.
- Next, divide both sides of the inequality by 10 to solve for w: 10w/10 ≥86/10.
- Simplify the equation: w≥8.6.
- Therefore, the correct solution to the inequality is w greater than or equal to 8.6.
