It is recommended that one fire fire extinguisher be available for every 6000 square feet in a building write and solve an equation to determine x the number of fire extinguishers needed for building that has 135,000 square feet?

In this question, it is given that

It is recommended that one fire fire extinguisher be available for every 6000 square feet in a building .

And X is the number of fire extinguishers needed for building that has 135 ,000 square feet area .

We have to find the value of X.

And for that we have to divide 135000 by 6000,that gives

So approx 23 fire extinguishers are needed for an area of 135000 square feet .

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
