The terms which are in both numerator and denominator will be cancelled out as there is not exponents involved so the result will be a/e

Further explanation:

We have to evaluate the expression

Given expression is:

\frac{a}{b}*\frac{b}{c}*\frac{c}{d}*\frac{d}{e}

We can also write the expression as:

\frac{a.b.c.d}{b.c.d.e}\\

The terms that are both in numerator and denominator will be cancelled out.

So the final expression will be:

\frac{a}{e}

The terms which are in both numerator and denominator will be cancelled out as there is not exponents involved so the result will be a/e

a store is having a sale on chocolate chips and walnuts. for 9 pounds of chocolate chips and 7 pounds of walnuts, the total cost
Ratling [72]

Answer:

The cost for each pound of chocolate chips is $2.75 and the cost for each pound of walnuts is $3.75.

Step-by-step explanation:

9x+7y=51

3x+5y=27

----------------

9x+7y=51

-3(3x+5y)=-3(27)

-------------------------

9x+7y=51

-9x-15y=-81

-------------------

-8y=-30

8y=30

y=30/8

simplify,

y=15/4

9x+7(15/4)=51

9x+105/4=51

9x=51-105/4

9x=(204-105)/4

9x=99/4

x=(99/4)/9

x=(99/4)(1/9)=99/36

simplify

x=2.75

So the cost for each pound of chocolate chips is $2.75 and the cost for each pound of walnuts is $3.75.

A bus on a regular schedule takes 3 1/4 hours to reach its destination. The express bus takes 2 1/2 hours to make the same trip.
RSB [31]
Time taken by a regular bus to reach its destination = 3 1/4 hours
                                                                                   = 13/4 hours
Time taken by the express bus to make the same trip = 2 1/2 hours
                                                                                       = 5/2 hours
Time that can be saved by taking the express bus = (13/4) - (5/2) hours
                                                                                 = (13 - 10)/4 hours
                                                                                 = 3/4 hours
So 3/4 hours can be saved by taking the express bus rather than the regular bus. The correct option among all the options given in the question is option "C". I hope the procedure is simple enough for you to understand.
