Answer:
The false choices are A, C, and E
Step-by-step explanation:
Let's make an example:
p=1
q=2
s=sqrt(3)
t=sqrt(6)
Since pq=1*2=2, the answer is rational and A is false.
Since pt=1*sqrt(6)=sqrt(6), the answer is irrational and B is true.
Since p/q=1/2=0.5, the answer is rational and C is false.
Since st=sqrt(3)*sqrt(6)=sqrt(18), the answer is irrational and D is true.
Since s/t=sqrt(3)/sqrt(6)=sqrt(1/2), the answer is irrational and E is false.

Step-by-step explanation:
I am not quite sure if this is correct.
first I figured out how many minutes per 1 mile: 24
then I figured out how exactly much time 1.5 hours is: 1 hour and 12 minutes. then I subtracted that from 2 hours, knowing that 1.5 hours is 3 miles, I found that there was only 48 minutes remaining in that hour, which would be 24×2, aka 2 miles. so the final answer would be 5 miles, sorry for the run-on sentence. Yet again, I am not quite sure if this is right-

Answer:
x+3y = 6
or, x = 6-3y.................(1)
3x+5y =6..........(2)
Substituting x = 6-3y in equation (2),
3 (6 - 3 y)+5 y =6
or, 18 - 9y +5y=6
or, y = 3
x = 6 - 3y = 6- 3.-3 = -3
