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;

Multiplying Eqn 2 by 8;

Subtracting Eqn 3 from Eqn 4;

Dividing both sides by 36;

Putting y=3 in Eqn 3;

Dividing both sides by 48;

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

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.
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>.
