A 60 gallon tank is full of water when it begins to leak at a rate of 2 gallons per minute. How long will it take for the tank to reach 12 gallons? A. 60 + 2x = 12
B. 60 = 12 + 2x
C. 12x – 2 = 60
D. 60 - 2x = 12

24 minutes

Step-by-step explanation:

60 - 12 = 48

48/2 = 24

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
