a water tank is draining at a constant rate if after five minutes the tank is drained by 4.5 gallons what is the rate in gallons
vova2212 [387]

Answer:

The rate is 0.9 gallon per minute

Step-by-step explanation:

Here, we have 4.5 gallons drained in 5 minutes but we are interested in calculating the rate per minute

Let the amount drained per minute be x

4.5 gallons = 5 minutes

x gallon = 1 minute

Let’s cross multiply;

x * 5 = 4.5 * 1

5x = 4.5

x = 4.5/5

x = 0.9 gallons

If x² - y² = 55, and x - y = 11, then y =<br> a. 8<br> b. 5<br> c. 3<br> d. -8<br> e. -3
irina1246 [14]
X^2-y^2=55
this means that 
(x+y)(x-y)=55
we know that x-y=11 so we can write
(x+y)(11)=55
x+y=55/11 we divide by 11 and we obtain 
x+y=5

x-y=11 this means
x=y+11 we replace in the other equation (x+y=5)

y+11+y=5
2y=5-11
2y=-6
y=-3
and you find out that also 
x=8
