Answer:

90 minutes long

1 hour, 30 minutes

Step-by-step explanation:

The science class begun 1:30pm and ends 3:00pm

An hour is 60minutes.

Between 1:30pm and 2:00pm is 30minutes.

And from 2:00pm to 3:00pm is an hour, that is 60minutes

We therefore have 30minutes+60 minutes=90 minutes long.

We can also say an hour, 30 minutes

2x-8y=-4
x-4y=-2
-4y=-x-2
y=(1/4)x+(1/2)
some values aer
x=0, y=1/2
x=-2, y=0
