3(2+4x)=−7x2<br> please give step by step and end with improper fraction as answer
SVETLANKA909090 [29]

Answer:

\frac{-5}{3}

Step-by-step explanation:

3(2 + 4x) = -7 x 2  Distribute the 3

6 + 12x  = -14  Subtract 6 from both sides of the equation

12x = -20  Divide both sides by 12

x = \frac{-20}{12}  Divide the top and the bottom of the fraction by 4

x = \frac{-5}{3}

Man Street Florist charges
Digiron [165]

Answer:

2 dozens, $41

Step-by-step explanation:

Given data

Man Street Florist charges

$18 for a dozen roses and a

$5 delivery fee

let the number of dozens be x

and the total charge for x dozens be y

hence

y= 18x+5--------------1

Blooms and Bouquets

charges $20 for a

dozen roses and a $1

delivery fee.

let the number of dozens be x

and the total charge for x dozens be y

hence

y= 20x+1 -------------2

Equate 1 and 2 we have

18x+5=20x+1

20x-18x= 5-1

2x= 4

x= 4/2

x= 2

Hence the number of dozens is 2

the cost is (put x= 2 in eqn 1 or 2)

y= 20(2)+1

y= 40+1

y= $41
