I think I would first convert it to hours to solve it and then back to minutes at the end. Super strange it’s been asked for in minutes.
So to convert 20 minutes into hours, you need to multiply by 3.
This means you need to do the same to the other side, cause if they’ve travelled 2.5 miles in 20 minutes, they’d travel 3 times that in an hour.
So this is 7.5m/ph
But then they want it in minutes, so I suppose 7.5/60?
So 0.125m/pm?
8x-2=-9+7x
Add 2 to both sides
8x=-7+7x
Subtract 7x from both sides
x=-7
Area of one wall = 14×8=112sqft
112 sqft ×4=448sqft

Answer:
5
Step-by-step explanation:
A device extracts 37 liters of water per day
Therefore the number of days it will take to extract 185 liters can be calculated as follows
= 185/37
= 5
Hence it would take 5 days
Answer:
x^2 -10x - 15 = 0
(don't know how far you want me to go)
Step-by-step explanation:
(x - 5)^2 = 40
(expand the brackets)
(x - 5)(x - 5) = 40
x^2 -5x -5x + 25 = 40
x^2 -10x + 25 = 40
x^2 -10x - 15 = 0
