Answer:

(3,3)

x=3 and y=3

Step-by-step explanation:

The system of equations are:-

3x - y = 6

6x + y = 21

Elimination method: To eliminate one variable by add/sub both equation and solve for another variable.

3x - y = 6

6x + y = 21

Add both equation and eliminate y

3x + 6x = 6 + 21

       9x = 27

          x = 3

Put x=3 into 6x + y = 21

6(3) + y = 21

18 + y = 21

      y = 21 - 18

      y = 3

Hence, The solution of the system of equations is (3,3)

How do u do 389.2÷28 in 5 grade standard algorithm show work
Mashutka [201]

Answer:

  see attached

Step-by-step explanation:

Each digit of the quotient is aligned with the least significant digit of the current dividend. The "current dividend" is that portion of the remaining dividend that is at least 1 and less than 10 times the divisor. The product of the quotient digit and the divisor is subtracted from the "current dividend" to get the remaining dividend.

__

For many folks, the hardest part of this algorithm is determining the appropriate quotient digit, and multiplying that by the divisor. Some teachers teach that you start this process by making a list of the multiples of the divisor:

N . . . 28N

1       28

2      56

3      84

4      112

...

This process can be aided by your number sense.

2N is simply N added to itself.

3N is N+2N.

4N is double 2N

5N is half of 10N.

You can proceed to build the table by adding 28 to each previous value, or by recognizing doubles and halves and other sums.

What is DE ?<br><br> Enter your answer as a decimal in the box.<br><br><br> ____ units
Fantom [35]
<span>6.3 Looking at the triangle, you can see that point D bisects line segment AB and that point E bisects line segment BC. In fact, you can easily determine that triangles ABC and DBE are similar triangles with DBE having sides that are half the length of the respective sides in ABC. And since line segment DE corresponds to line segment AC which is 12.6 units long, line segment DE is 12.6/2 = 6.3 units long.</span>
