Answer:
5
Step-by-step explanation:
3(2x-5)-2=x+8
6x-15-2=x+8
6x-17=x+8
6x-x-17=8
5x-17=8
5x=8+17
5x=25
x=25/5
x=5
Yes, because there are 36 inches in a yard so 36x2 equals 72 and when you add 19 to 72 you get 91.
Let the speed off the walk way be x and speed of the walkway be y
x+y=6....i
x-y=2....ii
adding the above equation we get:
2x=8
thus
x=4 ft/s
and
y=6-4=2 ft/s
thus the speed off the walk way is 4 ft/s
the speed of the moving walkway is 2 ft/s
