Counting by Tens with numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 Counting by Tens with words ten, twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety, one hundred Number Patterns when counting by Tens When you count by tens the numbers create a pattern. All the numbers end with a zero. The first digits are just like the numbers when you count (1, 2, 3, 4, 5, etc.). This pattern gives the numbers 10, 20, 30, 40, 50, etc. found from: http://www.aaamath.com/k4c_cox1.htm

≠A student took a system of equations, multiplied the first equation by and the second equation by , then added the results toge
Mandarinka [93]

Answer:

C. 3x+6y=9  and-2x-4y=4

Step-by-step explanation:

Given

Steps:

  • Multiply equation 1 by 2
  • Multiply equation 2 by 3
  • Add the results together

The attachment completes the question

(a): -2x+4y=4 and -3x+6y=6

Multiply by 2: -2x+4y=4 ===> -4x + 8y = 4

Multiply by 3: -3x+6y=6 ===> -6x + 12y = 12

Add together

-4x - 6x + 8y + 12y = 4 + 12

-10x + 20y = 16

B. 3x+y=12  and -3x+6y=6

Multiply by 2: 3x+y=12 ===> 6x + 2y = 24

Multiply by 3: -3x+6y=6 ==> -9x + 18y = 18

Add together:

6x - 9x + 2y + 18y = 24 + 18

-3y + 10y = 42

C. 3x+6y=9  and-2x-4y=4

Multiply by 2: 3x+6y=9 ===>6x + 12y = 18

Multiply by 3: -2x-4y=4 ===> -6x - 12y = 12

Add together:

6x - 6x + 12y - 12y = 18 + 12

0 = 30

This is the equation the student could have used because 0 = 30 means the equation has no solution.

-5x6(3x2 - 12x + 30)
defon

I belive its

-5 × 6( 3 × 2 - 12x + 30 )

-5 × 6( 6 - 12x + 30 )

-5 × 6( -12x + 36 )

-30 ( -12x + 36 )

From this point you distribute (-30)

( 360x + -1,080 )

Then divide 360 from x and -1,080, to get -3 = x or i guess -3x then divide -3 by -3 to get just x by itself

Im not sure hope this helpes
