Wittaler [7]
The tub holds 43 gallons.....it contains 18.....(43 - 18) = 25....so it needs 25 gallons.....after 5 minutes, the tub is full.....so it fills at a rate of 25/5 = 5 gallons per minute

y = 5x + 18....where y is the total gallons and x is the number of minutes
but we need it in standard form....

y = 5x + 18
-5x + y = 18
5x - y = -18 <== standard form

Answer:

x= 12  y= -3

Step-by-step explanation:

Rearrange.

x+y=9

x-y=15

Get x by itself, cancel out the y's and you'll get this:

2x=24

x= 12

Plug it in.

12+y=9

Get y.

y= -3

Check your work. I hope this helped.

nadya68 [22]

Answer:

38%

Step-by-step explanation:

Original price = $ 80

Price after reduction = $ 49.60

Reduction = 80 - 49.60  = $30.40

Percentage of decrease = \frac{reduction price}{original price}*100

                                         = \frac{30.40}{80}*100\\\\=\frac{3040}{80}

                                          =  38%
