5 0

Answer:

7.8125 gallons

Step-by-step explanation:

Because 5 gallons would cover 1600 square-foot wall so 1 gallon would cover:

1600 / 5 = 320 square-foot wall.

So to cover 2500 square foot-wall, we need in total of:

2500 / 320 = 7.8125 gallons of paint

Unit 6 lesson 9: linear functions sample work
loris [4]

Answer:

Initially, you have 2573 pieces.

You use 5 pieces each minute.

Right when you start, you have 2573 pieces.

One minute after that, you have 2573 - 5 pieces.

Another minute after, you have 2573 - 2*5 pieces.

Another minute after, you have 2573 - 3*5 pieces.

And so on.

You can see the pattern here, and with this, we can find the linear equation that represents the number of pieces that you have as a function of time.

Then, if the variable t represents the number of minutes that passed since you started, we can write the equation:

f(t) = 2573 - 5*t

That represents the number of pieces that you have after t minutes.
