\large -6x+6y=6<br> \large 6x+3y=12
Kaylis [27]

Answer:

the solution of the system is:

x = 1 and y = 2.

Step-by-step explanation:

I suppose that we want to solve the equation:

-6*x + 6*y = 6

6*x + 3*y = 12

To solve this, we first need to isolate one of the variables in one of the equations.

Let's isolate y in the first equation:

6*y = 6 + 6*x

y = (6 + 6*x)/6

y = 6/6 + (6*x)/6

y = 1 + x

Now we can replace this in the other equation:

6*x + 3*(1 + x) = 12

6*x + 3 + 3*x = 12

9*x + 3 = 12

9*x = 12 - 3 = 9

x = 9/9 = 1

Now that we know that x = 1, we can replace this in the equation "y = 1 + x" to find the value of y.

y = 1 + (1)  = 2

Then the solution of the system is:

x = 1 and y = 2.

Why do banks give out there credit cards easily and offer to reward tgem
Masteriza [31]

Answer:

If the cardholder has a participating cash back rewards program, the credit card issuer simply shares some of the merchant fees with the consumer. The goal is to incentivize people to use their credit cards when making payments rather than cash or debit cards, which earns them no rewards.

"Ten subtracted from the quotient of a number<br> and 5 is 18."
Anika [276]

Answer: n/5 - 10 = 18: this would be the equation. Your answer would be 140.

Step-by-step explanation: Let consider the number as ‘X’

Quotient of a number and 5 can be written as

                        X divided by 5

Ten subtracted from the quotient of a number and 5 can be written as

                       (X divided by 5)-10

Ten subtracted from the quotient of a number and 5 is 18 can be written as

                       (X divided by 5)-10=18

  By solving the above equation, find ‘X’

                       (X divided by 5) = 18 + 10

                    X/5=28

                       X = 28 x 5 = 140

How many dozen donuts are there in 46.2 donuts
m_a_m_a [10]
Hello there! We can answer through division here, given there are 12 donuts in a dozen:

46.2 divided by 12 gives us 3.85 dozens. However, there cannot be a fraction of a dozen in representation of a whole. Rounding to the nearest dozen, we will find that there are about 4 dozens in 46.2 donuts.

For there to be a value of 46.2 donuts, there had to have been more donuts to start with in the dozen. Therefore, we would round up. If there were 3 dozens, that would give us 36 donuts, which would not make sense because there are 46.2 present.

Hope this helps!
