The system of equations that can be used to determine the number of tetra fish and goldfish purchased is:
x = 2 y. 2 x + 1.5 y = 20
<h3>What are the system of equations ?</h3>
In order to determine the required values, two linear equations would be formed from the question. The two equations would exhibit the relationship between the two types of fishes:
The first equation would show the ratio between the two types of fishes bought: 2y = x
Th second equation would show the total cost of the two type of fish:1.5y + 2x = 20

Answer:
Step-by-step explanation:
we have
where
Q -----> is the daily output
A -----> is the number of people
For Q=621
Find the value of A
substitute and solve for A
Subtract 600 both sides
squared both sides
Subtract 41 both sides
Rewrite
600,000,000+ 70,000,000+ 200,000+ 600+ 40
