Answer:
The answer is 0.25
Step-by-step explanation:
(1)we group like terms by subtracting 32.50 by 28.75
(2) we subtract 20 and 5 to give us a value of 15
(3)when we subtract 32.50 and 28.75 we get a value of 3.75
(4)so the equation will look like this 3.75t = 15
(5)we divide 3.75 we both the two equations
(6)With a correct calculation, Your answer should be t = 0.25
Answer:
24
Step-by-step explanation:
distance = rate times time.
Here the distance covered by the first train is (70 km/hr)t (t=# of hours), and that by the second train is (85 km/hr)t.
Add these together and set the sum equal to 620 km:
70t + 85t = 620, or 155t = 620, or 4. It will take 4 hours for the distance between the two trains to increase to 620 km.
Answer:
-2
Step-by-step explanation:
because the slope is 2, a perpendicular line must be the inverse
the equation for y1 is y=2x+1
y2= -2y+1
