How do I determine the number of solutions there are for this system of equations?2x+6y=5 x+3y=2

1 answer:

5 0

Take one of the equation and, 2X+6y=5 and x+3y=2, now take one of the equation and (-2) x+3y=2 then -2x-6y=-4 add the common factor with the other equation which would cross out both variable leaving 0=1

Lars deposited $50 into a savings account for which interest is compounded quarterly. According to the rule of 72, what interest

Ivanshal [37]

Answer: C 2.5%

Step-by-step explanation:

The "Rule of 72" is a easy way to calculate how much time an investment will take to double with a given fixed annual rate of interest.

Just we have to divide 72 by the annual rate of return(r), we can get a rough estimate of how many years it will take to double the initial investment .

Now, in given problem: Let 'r' be the rate of interest

Time to double the amount=29 years

Thus by rule 72 ,

$\frac{72}{r}=29\\\Rightarrow\ r=\frac{72}{29}=2.4827\%\approx2.5\%$
