A system of equations is shown below:

1 answer:

6 0

To solve this problem you must apply the procceddure shown below:

1. You have the following system of equations:

x+y = 3
2x–y = 6

2. Then, you must clear the variable y from the first equation and susbtitute it into the second equation, as below:

x+y=3
y=3-x

2x-y=6
2x-(3-x)=6
2x-3+x=6
3x=6+3
3x=9

3. Therefore, the value of x is:

x=9/3
x=3

4. As you can see, the correct answer is:

x=9

What is the the distance between a point at (-3,4) and a point at (2,-5)

zaharov [31]

<h2>Question:-</h2>

What is the distance between a point at (-3,4) and a point at (2,-5) ?

<h2>Solution:-</h2>

Let the two points be A and B .

And, let the distance be P .

Now, the distance P between the point A (-3,4) and the point B (2,-5) is

$\bf P \: = \sqrt{(-3 \: - \: 2)^2 \: + \: (4 \: + \: 5)^2}$

$\implies$ $\bf P \: = \sqrt{(-5)^2 \: + \: (9)^2}$

$\implies$ $\bf P \: = \sqrt{25 \: + \: 81}$

$\implies$ $\bf P \: = \sqrt{106}$

$\implies$ $\bf P \: = \: 10.3$

Can you show me the steps when reducing 58/48 to 29/24?

klemol [59]

Answer:

58/48 to 29/24

Step-by-step explanation:

An easy way that I always remember is that if both the numbers are even, divide by 2. Keep dividing until you get a odd number and then you know that you have your lowest form.
