Answer:
y=-2x+7
Step-by-step explanation:
The Slope is obviously -2, and just add a random y and play around with it until it goes through the point (5,-3)
84.615 % or 85% rounded. divide 55/65 to get that answer! :)
Let the speed of car be x km/h
speed of train=x+5 km/h
distance=speed*time
thus distance covered by car:
x*4=4x km
distance covered by train:
7(x+5) km
total distance:
4x+7x+35=255
11x=255-35
11x=220
x=20 km/h
speed of train=20+5=25 km/hr
The two equations are above. It is better to go to Ice Plex for skates under five hours and Skate World for skates over five hours.
3/10 of an hour is 6x3=18 mins
To get to one hour we do 3/10 x 10 / 3
So we 1/6 x 10 / 3 = 10/6 / 3 =5/3 / 3=5/9
