103+53=156
156/2=78
The average or mean is 78
Answer:
Width=75
length=105
Step-by-step explanation:
Width=x
length=30+x
= 7875=x*30+x
x^2+30x-7875=0
x^2+105x-75x-7875=0
x(x+105)-75(x+105)=0
785.63-(57+125)
=785.63-182
=603.63
603.63+57.25=$660.87
Answer:

Step-by-step explanation:
Speed = Distance/time
Therefore time must = distance/speed
Since the two students are running apart from eachother, we can add their speeds together.
Also we can subtract 10 feet from our goal of 1870 since they're already 10 feet apart.
1860 feet/(150+1650) feet per minute
We can cancel out the feet since it's a common term.
And we're left with 6 minutes.
