-1/3x-4/3y=2

1/3x-2/3y=4

First realize that the coefficient of x is -1/3 and 1/3 which can be eliminated with addition

Adding the two equations together gets

-6/3y=6

Simplify

-2y=6

y=-3

Substitute back into original equation

1/3x-2/3(-3)=4

1/3x+2=4

1/3x=2

x=6

Answer

x=6, y=-3

Check answer

-1/3(6)-4/3(-3) =?= 2

                -2+4=2

                     2=2

Done!

Nataliya [291]

Answer:

Option D.

Step-by-step explanation:

The total stock of currency and other liquid instruments circulating in the economy of a country as of a particular time is known as money supply.

If the reserve requirements of banks is least then banks are able to loan more money, that will increases the overall supply of money in the economy.

In 100% reserve banking system, 100% amount of each depositor's funds would be required to keep by bank for immediate withdrawal on demand.

100% reserve banking system is also known as Full-reserve banking system.

It means, if a customer deposits $100 of currency into a bank with 100% reserve banking system, then the money supply remains the same.

Therefore, the correct option is D.

1/4 miles to a shoe store. Then you walk another 2/5 miles to a music store. How many miles have you walked in all?
zavuch27 [327]

Answer:

\frac{13}{20}

Step-by-step explanation:

\frac{1}{4}  +  \frac{2}{5}

First, we need to make the demoninators the same so we times 4 by 5 and whatever we do to the bottom, we do to the top, and 5 by 4.

\frac{ 1 \times 5}{4 \times 5}  +  \frac{2 \times 4}{5 \times 4}

\frac{5}{20}  +  \frac{8}{20}

=  \frac{13}{20}

demoninator now doesn't change unless you're multiplying or dividing.
