Is b = 5 a solution to the inequality below?
b<1
yes
no

No

Step-by-step explanation:

The given inequality is b < 1.  We determine whether or not b = 5 is a solution by substituting 5 for b and asking ourselves whether the resultant inequality is true or not:

5 < 1 is FALSE and so b = 5 is NOT a solution of the given inequality.

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
