For a system of equations to have infinitely many solutions it must describe identical lines.
If you multiply the first equation by 2, then move the x term to the left side, you would get 2y-4x=-10
Final Answer:
-10

Answer:
5000 Australian Dollars
Step-by-step explanation:
To find out how many Australian dollars need to be sold, we first need to find the profit of a single dollar sold.
We will be using the formula for profit, which is:
Profit = Total Revenue - Total Cost
Now we define the available variables.
Total Revenue = 81.40
Total Cost = 80.20
Profit = 81.40 - 80.20
Profit = rs 1.20/dollar
Now we have to find how many dollars we have to sell to get a profit of rs 6000.
We simply divide the amount of profit that we want to the price per dollar.
Total Profit = 6000
Profit per dollar = 1.20
This give us:
6000 / 1.20 = 5000 Australian Dollars.
3:8 is equivalent to 12:32 multiplying by 3 to 12 is 4, so you multiply each number to 4. 3 x 4 = 12 8 x 4 = 32 yes 3:8 is equal to 12:32.
