Answer: x ≥ -1
<u>Step-by-step explanation:</u>
4(2x - 3) ≥ 4(x - 4)
8x - 12 ≥ 4x - 16 <em>distributed 4 into 2x - 3</em>
4x - 12 ≥ -16 <em>subtracted 4x from both sides</em>
4x ≥ -4 <em>added 12 to both sides</em>
x ≥ -1 <em>divided both sides by 4</em>

Answer:
If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour
Step-by-step explanation:
Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).
1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.
