Answer:
None
Step-by-step explanation:
If 1/3 is left every hour then it would then after 3 hours wouldn't it be gone? Most would assume if only a third of the water is left every hour then after three hours there would be either of two answers if the question was written correctly: one third because they refilled it on the 2nd hour or none because it wouldn't even last two hours
Error is between steps 4 and 5. It should say:
Step 4: -9x < 27
Now divide by -9
Step 5: x > -3
Note that the inequality changes direction.
When you mean multiply or divide an inequality by a negative number, the inequality changes direction.
For example:
4 < 5
Multiply by -1:
-4 > -5
Another example:
-5 < 0
5 > 0
Answer:
80 hours for 2 workers to build 8 cars
Step-by-step explanation:
2 cars / 8w *5 hr = 2 cars / 40 hrs 1 car takes 20 hrs
8 cars * 20 hours = 160 hours required
two workers split this time 160/2 = 80 hours
L = 5W - 10
5W = L + 10
W = 1/5(L + 10)
Area = L x W
240 = L(1/5(L + 10)
L^2 + 10L = 240(5) = 1200
L^2 + 10L - 1,200 = 0
