Answer:

42300000

Step-by-step explanation:

Use known fact

1\ km=1000\ m

Consider 1 square kilometer:

1\ km^2=1\ km\times 1\ km=1000\ m\times 1000\ m=1000000\ m^2

So, to find the answer, you have to multiply given number of square kilometers by 1000000:

42.3\ km^2=42.3\times 1000000\ m^2=42300000\ m^2

what is the solution to this system of equations (Use the elimination method by multiplying the first equation by 3.) 2x+y=20 6x
user100 [1]

Answer:

(7, 6)

Step-by-step explanation:

multiply first eq. by 3 to get 6x - 3y = 60

now do

6x + 3y = 60

- 6x - 5y = 12

--------------------

8y = 48

solve for y: y = 6

with this y value, plug it in to the first equation (easier to solve) and get 2x + 6 = 20

solve for x and get x = 7

so ans is (7, 6)
