Maria's book is longer than brandon s. then's. the difference in the two book lengths is 56pages. the total amount of pages in both books! maria's and brandon's books. ks together is 348. find the lengths of

Let the length of maria's book be a and that of Brandon's be b.

So, by the question,

the difference in length of books is 56

i.e. a-b=56(1)

and the length of books all together is 348

i.e. a+b=348(2)

Adding (1) and (2);

(a-b)+(a+b)=56+348

or, a-b+a+b=404

or, 2a=404

or, a=202

substitutting the value of a in (2),

202+b=348

or, b=146

therefore, the length of Maria's book is 202

and the length of Brandon's book is 146.

78.59 is the mean
