Answer: Option <span>C. To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by -3. The solution to system B will be the same as the solution to system A.
First equation of system A multiplied by -3:
(-3)(x+6y=5)
(-3)(x)+(-3)(6)=(-3)(5)
-3x-18=-15
Sum of the second equation of system A and the first equation multiplied by -3:
(-3x-18)+(3x-7y)=(-15)+(-35)
-3x-18+3x-7y=-15-35
-25y=-50
System B
x+6y=5
-25y=-50 </span>
It’ll be the one on the far right last one ;)
3,000 is 10 times as much as
3000 = 10 times of what number
We need to find 10 times what number gives us 3000
Let the unknown number be x
3000 = 10 times x
3000 = 10x
To solve for x, we divide by 10 on both sides
300 = x
So, the unknown number is 300
3000 = 10 times 300
3000 is 10 times as much as 300
I think the answer is either B or C I am not completely sure but I got 36
The summary of the ruler placement postulate is given as:
- there is a one-to-one correspondence between the set of points on the line and the set of real numbers, and.
- the distance between two points equals the absolute value of the difference between the corresponding numbers.
<h3>What is the ruler placement postulate?</h3>
This states that the points of a line can be matched and correspond to a set of points on the line and the set of real numbers,
Therefore, based on the fact that your question is incomplete, a general overview of the ruler placement postulate is given to give you a better understanding of the concept.
