Answer:
your answer is 15.6
Step-by-step explanation:
5x divided by 3= 26
multiply 3 by each side
5x = 78
divide 5 by each side to get x by itself
x= 15.6
Vertical reflection over the x-axis, shrink of 1/3, right 3, up 2
Y=9x-2
3x-2y=7
3x-18x+4=7
-15x=3
x=-1/5
y= -19/5
So if you go 720 miles in 8 hours, you would travel at a speed of:
720 miles / 8 hours = 90 miles per hour.
So in 1 hour, you would have traveled:
90 miles per hour * 1 hour = 90 miles.
