60t+20t=150
80t=150
t=150/80=15/8
Note: t is only half the time, the total time is 15/4=3 hours 45 minutes
They gave you the slope and one point, m = 5 and (2, 3) so we have a formula that is,
y - y1 = m(x - x1) the 1s are under and then you simplify plug them in and find the answer
y - 3 = 5(x - 2)
y - 3 = 5x - 10
y = 5x - 10 + 3
y = 5x -7. << your answer
hope this helped, blessings!
Try this: Combine 6 and 9, obtaining 15.
Compare this sum, 15, to the length of the 3rd side: 15.
If placed end to end, the 2 sides with lengths 6 and 9 form a new line of length 15. We'd end up with this new line superimposed on the 3rd side (with length 15).
Think: Do 2 straight lines of length 15, superimposed on one another, form a triangle?
