In 20 hours because 200x20 is 4,000
Answer:
Use math way because it is a good way to solve it
Answer:
w ≤ 13
Step-by-step explanation:
-2(w-4) ≥ -18
Divide both sides by -2:
w-4 ≤ -18/-2
Don't forget to turn the inequality around, because we divided by a negative number!! We had greater than, now we have less than.
w-4 ≤ 9
Add 4 to both sides:
<u>w ≤ 13</u>
