Step-by-step explanation:
<u>Step 1: Define</u>
2(3x - 1) ≥ 4x - 6
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 2: 6x - 2 ≥ 4x - 6
- Subtract 4x on both sides: 2x - 2 ≥ -6
- Add 2 on both sides: 2x ≥ -4
- Divide 2 on both sides: x ≥ -2
Here we see that any value <em>x</em> greater than or equal to -2 would work as a solution.

Answer:
95 seconds
Step-by-step explanation:
At 5 seconds per box, pulling 3 boxes takes 3×5 = 15 seconds.
At 1 second per envelope, pulling 10+10+60 = 80 envelopes takes 1×80 = 80 seconds.
The total time required to provide the required envelopes is 15 +80 = 95 seconds.
