Given the following system of equations: 2x + 6y = 12 4x + 3y = 15 Which action creates an equivalent system that will eliminate one variable when they are combined? Multiply the second equation by −2 to get −8x − 6y = −30. Multiply the first equation by 2 to get 4x + 12y = 24. Multiply the second equation by −4 to get −16x − 12y = −60. Multiply the first equation by −4 to get −8x − 24y = −48.

Answers

Answer 1
Answer:

Answer:

Multiply the second equation by −2 to get −8x − 6y = −30.

Step-by-step explanation:

we have

----> first equation

----> second equation

Solve by elimination

Multiply the second equation by -2 both sides

---> equivalent second equation

Adds first equation and the equivalent second equation

Find the value of y

substitute the value of x in any of the equation

the solution of the system is the point (3,1)

What is 423.408 rounded to the neatest hundredth

Answers

The hundredth is the second decimal place. You know the rounding rules are where you look at the previous place and if it's 5 or above the number place your rounding to goes up. So the answer is 423.41
423.408 = 423.41
0.08 is nearer to 0.1 than 0.001

6 is 3% of what number?

Answers


✡ Answer: 200✡

- - Solve:

✡ First we need to find the formula to solve:
(3)/(100) * x=6


✡ Now:
x is equal to: (100*6)/(3)


✡Now we are going to multiply 100*2 to get our answer.

- - 100*2=200


✡Hope this helps!✡

6 is 3 percent of the number 200.

To find the number that 6 is 3% of, we can use the concept of percent as a ratio.

Let's represent the unknown number as "x".

We can set up the equation:

3% of x = 6

To solve for x, we need to divide both sides of the equation by 3% (which is equivalent to dividing by 0.03):

(3% of x) / 0.03 = 6 / 0.03

Simplifying further:

x / 0.03 = 200

To isolate x, we can multiply both sides of the equation by 0.03:

x = 0.03 * 200

x = 6

Therefore, 6 is 3% of the number 200.
