A 450-gallon tank full of water is draining at a rate of 20 gallons per minute. • How many gallons will be in the tank after 7 minutes?

• How long will it take for the tank to have 200 gallons?

• Write an equation that represents the relationship between the gallons of water in the tank and the minutes the tank has been draining.

- 310 gallons

- 12.5 minutes

- y=450-(20x)

where y is the gallons left and x is minutes

Step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
