A principal is the amount of money you invested or deposited, so in this case, the principal is $3,000,
(and the net amount of money you earn is the interest, that is $300 in this one.)
Answer:
Infinitely many solutions
Step-by-step explanation:
If we have a system of equation like:
2x+y=4
6x+3y=12
If we make y the subject in the first equation and substitute into the second equation, we get:
6x+3(4-2x)=12
We expand to get:
6x+12-6x=12
6x-6x+12=12
Now the variable adds out to give:
12=12
This statement is true so the equation has infinitely many solution.
The answer is (2, sqr root 21). Hope this helps
You do 2x20 which is basically 2x2 (4) add a zero and your answer is 40
