Responses

w≥860
  w greater than or equal to 860

w≥51.2
  w greater than or equal to 51.2

w≥8.6
w greater than or equal to 8.6

w≥86

Answer 1

To solve the inequality \( 10w + 213 \geq 299 \), we can follow these steps:

1. Subtract 213 from both sides of the inequality:

   \[ 10w \geq 299 - 213 \]

   \[ 10w \geq 86 \]

2. Now, divide both sides by 10:

   \[ w \geq \frac{86}{10} \]

   \[ w \geq 8.6 \]

So, the solution to the inequality is \( w \geq 8.6 \).

The correct response is:

w≥8.6
w greater than or equal to 8.6
