Step-by-step explanation:
4/8 + 3/5 =7/13
4+3=7
8+5=13
7/13 that's the answer! I'm sorry if I'm wrong!
Answer:
Option D) ÷ 1,000
Step-by-step explanation:
we know that
One kilogram represent one thousand grams
1 kg=1,000 g
so
To convert grams to kilograms, divide by 1,000
To convert kilograms to grams, multiply by 1,000
In this problem is necessary to convert grams to kilograms
therefore
divide by 1,000

Answer:
c) -2y = 10x + 6
Step-by-step explanation:
The equation of a line in slope-intercept form is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
The variables stand for:
![y:$ y-coordinate of any point on the line\\$x:$ x-coordinate of any point on the lien\\$m: $ Slope of the line\\$b: $ y-intercept of the line; where the line meets the y-axis](https://tex.z-dn.net/?f=y%3A%24%20y-coordinate%20of%20any%20point%20on%20the%20line%5C%5C%24x%3A%24%20x-coordinate%20of%20any%20point%20on%20the%20lien%5C%5C%24m%3A%20%24%20Slope%20of%20the%20line%5C%5C%24b%3A%20%24%20y-intercept%20of%20the%20line%3B%20where%20the%20line%20meets%20the%20y-axis)
Plugging in the given information into the equation:
![y=-5x+(-3)\\y=-5x-3](https://tex.z-dn.net/?f=y%3D-5x%2B%28-3%29%5C%5Cy%3D-5x-3)
Go through the answer choices:
<u>a) 2y = -5x - 3</u>
Divide both sides of the equation by 2
![y=-\frac{5}{2}x-\frac{3}{2}\rightarrow\text{Incorrect!}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B5%7D%7B2%7Dx-%5Cfrac%7B3%7D%7B2%7D%5Crightarrow%5Ctext%7BIncorrect%21%7D)
<u>b) -2y = 10x - 6</u>
Divide both sides of the equation by -2
![y=\frac{10}{-2}x-\frac{6}{-2}\\y=-5x-(-3)\\y=-5x+3\rightarrow\text{Incorrect!}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B10%7D%7B-2%7Dx-%5Cfrac%7B6%7D%7B-2%7D%5C%5Cy%3D-5x-%28-3%29%5C%5Cy%3D-5x%2B3%5Crightarrow%5Ctext%7BIncorrect%21%7D)
<u>c) -2y = 10x + 6</u>
Divide both sides of the equation by -2
![y=\frac{10}{-2}x+\frac{6}{-2}\\y=-5x+(-3)\\y=-5x-3\rightarrow\text{Correct!}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B10%7D%7B-2%7Dx%2B%5Cfrac%7B6%7D%7B-2%7D%5C%5Cy%3D-5x%2B%28-3%29%5C%5Cy%3D-5x-3%5Crightarrow%5Ctext%7BCorrect%21%7D)
<u>d) 2y = 10x - 6</u>
Divide both sides of the equation by 2
![y=\frac{10}{2}x-\frac{6}{2}\\y=5x-3\rightarrow\text{Incorrect!}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B10%7D%7B2%7Dx-%5Cfrac%7B6%7D%7B2%7D%5C%5Cy%3D5x-3%5Crightarrow%5Ctext%7BIncorrect%21%7D)
Therefore the answer is c) -2y = 10x + 6
Additional Comments:
We can only divide both sides of the equation by 2 and/or -2 because of the Division Property of Equality. This property states that if we divide one side of the equation by a certain quantity, we must divide the other side by the same quantity so that the equation remains equal.
