Option C (None Of The Above)

Step-by-step explanation:

Given expression = $- (\frac{ - e}{ - f} )$

Lets multiply the numerator and denominator by -1.

$= > - ( \frac{ - e \times - 1}{ - f \times - 1} )$

$= > - ( \frac{e}{f} )$

Now , lets open the brackets.

$= > \frac{ - e}{f}$

But as this expression is not there in the given options , the correct answer will be Option C.

The florist charges $31.75 for eight roses and five carnations. For one rose and three carnations, it cost $5.75. What is the co

Sedbober [7]

Cost for a carnation is $0.75

Step-by-step explanation:

Let,

Rose = x

Carnation = y

According to given statement;

8x+5y=31.75 Eqn 1

x+3y=5.75 Eqn 2

$Multiplying\ Eqn\ 2\ by\ 8\\8(x+3y=5.75)\\8x+24y=46 \ \ \ Eqn\ 3\\Subtracting\ Eqn\ 1\ from\ Eqn\ 3\\(8x+24y)-(8x+5y)=46-31.75\\8x+24y-8x-5y=14.25\\19y=14.25\\Dividing\ both\ sides\ by\ 19\\\frac{19y}{19}=\frac{14.25}{19}\\y=0.75$
