Answer:
for four copies the cost is $72
Step-by-step explanation:
52 + 5a = 24 + 12a
28 + 5a = 12a
28 = 7a
a = 4
52 + 20 = 72
for four copies the cost is $72
Sure
Original Equation:
[-5x-16=9x+x-1]
Solve:
[-5x-16=10x-1]
Add (16) to both sides of the equation:
[-5x=10x+15]
Subtract (10x) from both sides:
[-15x=15]
Divide (-15) from both sides:
x=-1
This is a simple one.
We dont know how fast it is going downstream, but we do know it took 3 hours to reach the destination. Now, saying that, when coming back we know it took 4 hours(an hour longer than what we took to get there), and we also know we were moving 5 miles slower per hour. If we think a bit, we can see that moving 5 miles slower made us take a whole hour. Making me believe that when we were headed to our destination we were moving at 20 miles per hour, and when we were headed back, we moved at 15mph(20-5)
To check that this was correct, we can just simply check, "okay so from our point to our destination we traveled 60 miles in total. if we went 20 miles an hour, in 3 hours(3×20) we would be at our destination, and if we traveled at 15 miles an hour, it would take us 4 hours to get back to our starting point (4×15)
