Answer:
-1/4
Step-by-step explanation:
For this equation, first divide both sides by 1.2, to get x+4y=15. Then, subtract x from both sides. Now, with 4y=-x+15, divide by 4. You should get y=-1/4x+15/4 (15/4=3 3/4 or 3.75). The formula y=kx=b, where k is slope, means the slope is -1/4.
Alright, lets get started.
Jen picked three fourth in half an hour.
Half an hour means 30 minutes.
At the same rate, how many she can pick in 2 hours.
2 hours means
minutes
Now,
In 30minutes, Jen can pick = 
In 1 minute, Jen can pick = 
In 120 minutes, Jen can pick = 
Hence Jen can pick complete 3 in 2 hours of time.
So the answer is 3 : Answer
