A bouquet of 8

iren2701 [21]

A rose costs $2.5 and a carnation costs $3.

Step-by-step explanation:

Let,

Roses = x

Carnations = y

According to given statement;

8x+10y=50 Eqn 1

6x+12y=51 Eqn 2

Multiplying Eqn 1 by 6;

$6(8x+10y=50)\\48x+60y=300\ \ \ Eqn\ 3\\$

Multiplying Eqn 2 by 8;

$8(6x+12y=51)\\48x+96y=408\ \ \ Eqn 4$

Subtracting Eqn 3 from Eqn 4;

$(48x+96y)-(48x+60y)=408-300\\48x+96y-48x-60y=108\\36y=108$

Dividing both sides by 36;

$\frac{36y}{36}=\frac{108}{36}\\y=3$

Putting y=3 in Eqn 3;

$48x+60(3)=300\\48x+180=300\\48x=300-180\\48x=120$

Dividing both sides by 48;

$\frac{48x}{48}=\frac{120}{48}\\x=2.5$

A rose costs $2.5 and a carnation costs $3.

If you distribute a negative factor, should you flip the inequality symbol? And why be specific

Alchen [17]

You flip is when you mulitply the whole equation by a negative
not when you distribute a negative
if yo had
-3(x+4)>x
you wouldn't flip the negative symbol when distributing then -3

but if you had
-3(x+4)>-x
you would eventually have to multiply by -1 to make +1x

because they will be differente
exaple

12>3 is true
if yo multiply negative
-12>-3 is fale
-12<-3 is true

anothe rexample with placeholders
x<x+2
mulitply -1
-x>-x-2
false
-x<-x-2
true
that is why we flop the inequality symbole

1.5 in x 1.5 in

The scale factor is

Original to shirt = 1:8

Area of the logo on shirts

A = 1/2bh
A = 1/2*(1.5*8)(1.5*8) =72 in²
