Answer:
x=2
Step-by-step explanation:
first, let's distribute.
3(x+1)-2=x+5
3x+3-2=x+5
then, let's combine like terms.
3x+1=x+5
now, we subtract x on both sides.
2x+1=5
subtract 1 on both sides.
2x=4
divide by 2 on both sides.
x=2

Answer:
The problem does not work.
Step-by-step explanation:
The plane with speed of 31 mph will cover 640 miles in
hours.
Now, it burns 5 gallons of gas every 3 minutes i.e. 0.05 hours.
So, it will burn in 20.64 hours
gallons.
Now, the helicopter with speed of 45 mph will cover 640 miles in
hours.
Now, it burns 7 gallons of gas every 5 minutes i.e. 0.083 hours.
So, it will burn in 14.22 hours
gallons.
But both of them starts with only 80 gallons of fuel.
Therefore, the problem does not work. (Answer)
