Answer: OE
Step-by-step explanation: This is the only relationship in which one variable impacts the other
-1.5(4-n)+2.8
multiply 4-n by -1.5
multiply to both the 4 and -n
-6+1.5n+2.8
add -6+2.8 since they are similar
-3.2+1.5n
1.5n-3.2
I believe this is the simplest form
Answer:
no solution
Step-by-step explanation:
a solution would mean a point where the two lines cross. theres no such thing for parallel lines.
but if the lines are the same, they are parallel and cross everywhere, that would give infinite solutions.
if they would cross once, it would mean one solution
31.5749...9...9....9....9....
Since distance equals speed times time (d = st), we have
t = d/s
where d = 120 miles and s = 15 miles per hour
t = d / s
t = 120 / 15
t = 8
It will take 8 hours to drive 120 miles at a speed of 15 miles per hour.
