2n+9+5n=30 combine like terms on left side
7n+9=30 subtract 9 from both sides
7n=21 divide both sides by 7
n=3
Y = 14x is the equation you should use! Hope this helped.
Answer:
<, -4
Step-by-step explanation:
-8x-20<12
add 20 to both sides
-8x=32
divide both sides by -8

Step-by-step explanation:
The fox is faster. Because he is a fox.
Also because he can (assuming he doesn't fatigue or get caught by hounds in the second half of the hour) run 42 miles in 1 hour.
The rabbit runs 35 miler per hour.
Velocity = Distance/time
Fox velocity = 21 miles/0.5 hour
Dividing by 0.5 is the same as multiplying by 2, so...
Fox velocity = 42 miles/hour
