Answer:
value of x = 4
Step-by-step explanation:
here's the solution : -
=》6 - 2x = 5x - 9x + 8
shifting like terms aside,
=》6 - 8 = 5x - 9x + 2x
\_(●_●)_/
=》-2 = -2x
=》x = -2 / -2
=》x = 1

Answer:
1 1/2 miles
Step-by-step explanation:
if running 1 lap around a track is 1/2 miles then all we have to do is add it up
so we know that 1/2 miles is one lap
so if he runs two laps we would have run 1 mile
now that we know that he would have ran 1 mile in 2 laps then all we have to do it just add 1 more 1/2 mile in which would give u the answer of 1 1/2 miles or 1.5 miles
