Answer:
Well I can give you advice, so first ask yourself if you actually read the whole problem. Did you? okay then make sure you've looked closely at the data table. What does it mean? Then try to put it all together and see if you can figure it out yourself, and if your stuck then I would suggest coming back.
Step-by-step explanation:
Flip the situation:
X + 3.25 = 4.72
Subtract 3.25 from both sides
X + 3.25 - 3.25 = 4.72 - 3.25
X = 1.47
Graph 6:-1/3x+5
Graph 7:5/4x-12
Answer:
34 mph and 68 mph respectively
Step-by-step explanation:
Step one:
given data
let the speed of the first truck be x mph
and the speed of the second truck be 2x mph
time taken = 6 hours
total distance = 204 miles
Step two:
from speed = distance/time
distance= speed*time
hence
2x*6-6x= 204
12x+6x= 204
6x= 204
divide both side by 6
x= 204/6
x=34 mph
The second truck was moving at
=2x
=2*34
=68 mph
