It is recommended that one fire extinguisher be available for every 6,000 square feet in a building. write and solve an equation to determine x, the number of fire extinguishers needed for a building that has 135,000 square feet.

23 fire extinguisher.

Step-by-step explanation:

Let x be the number of fire extinguishers.

We have been given that one fire extinguisher be available for every 6,000 square feet in a building. So the total area covered by x extinguisher will be 6,000x.

Since the building has an area of 135,000 square feet. This means that that total area covered by x extinguisher is 135,000 square feet. We can represent this information in an equation as:

Therefore, the equation represents the number of fire extinguishers needed for a building that has 135,000 square feet.

Now we will solve for by dividing both sides of our equation by 6000.

Since we can not have 0.5 of a fire extinguisher, so we will round up our answer as:

Therefore, 23 fire extinguisher are needed for the building.

answer: a.   one is a factor of every whole number since every number is divisible by itself.
