The answer is 16.
First of all, you need to divide 4 by 1/4.
4/1 / 1/4 = 1.
15 - 1 + 2
Next, you go from left to right with addition and subtraction, so subtract 1 from 15 first.
15 - 1 = 14
14 + 2
Finally, add 14 and 2.
14 + 2 = 16.
Answer ↣ 12 gallons per minute
Step-by-step explanation ↣ Ok I'm gonna use ratios because I can't draw a graph here.
Ok so if the garden hose supplies 36 gallons of water in 3 minutes, then the ratio is 36:3 because every 3 minutes the garden hose "sprays" 36 gallons.
To simplify this ratio, you need find the amount of water the garden hose supplies in 1 minute.
Well to get from 3 to 1, you have to divide by 3.
Do the same thing to 36. 36/3 equals 12.
So the final ratio is 12:1
This is the unit rate. The unit rate is when one variable is 1 unit (most of the time it is speed).
You can multiply 1 by any number and multiply 12 by the same number.
Here are some ratios...
m=minutes
g=gallons
1m:12g
2m:24g
3m:36g
4m:48g
5m:60g
Hope this helped!
BTW why do I sound like this I'm not a aesthetic person-
Can you make is more Specific?
You use lots and lots of math.
1 + 1 = 2 - 1 = 1 hope this helps.
