104 is 8 times 13. but working 8 hours 7 days equals 56 times the hourly pay comes out to 728
The first thing we must do for this case is to define variables.
We have then:
x = cost of a hardcover book
y = cost of a paperback book
We write the system of equations:
3x + 7y = 29.50
2x + 5y = 20.50
The solution to the system is:
x = 4 $
y = 2.5 $
Answer:
the cost of a hardcover book is $ 4
Answer:
We can decompose a function into sum of fractions as well.
<em>" Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation " . </em>
<em>Ж</em><em> </em>Now first we will write an expression for \dfrac{3}{8}[/tex]
<em> Ж </em>Now the decomposition of 1 is given as:
And in many more ways we can decompose these numbers.
