Answer:

\frac{2}{5} \times\frac{4}{3}

Step-by-step explanation:
To find the answer we use KCF (Keep, Change, Flip).

\frac{2}{5} \div\frac{3}{4}
\frac{2}{5} =\frac{2}{5}
\div=\times
\frac{3}{4} =\frac{4}{3}
\frac{2}{5} \times\frac{4}{3}

Which means the expression used to find the answer would be "2/5 × 4/3."

Hope this helps.

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.

The graph shows the number of centimeters a particular plant grows over time. Given the points​ (0,0) and ​(6​,9​), how many cen
Irina18 [472]

Answer:

The correct answer is: the rate of change is 1 cm per 2 weeks, or 1/2.

Step-by-step explanation:

I found a graph with the same problem, so I guess this is the graph to be based on. To find the rate, just determine the slope between any two points along the line. Suppose these points are: (30,10) and (50,20).

Slope = (20 - 10)/(50 - 30) = 1/2

The correct answer should be: the rate of change is 1 cm per 2 weeks, or 1/2.

_______ marshes are the most diverse.<br> brackish<br> freshwater<br> salt<br> estuary
erik [133]

The <u>brackish</u> marshes are the most diverse.

<h3>What are Brackish Marshes?</h3>

These are the sectors that are found in the estuaries that border the coasts, which is why they contain fresh and salt water, which is usually called brackish, where a great diversity of animals live, both salt water and adaptable to brackish water.

Within the fauna of this sector, you can find the archer fish, the <em>Monodactylus argenteus</em> and <em>Scatophagus argus</em>.
