To solve this problem you must apply the procceddure shown below:
1. You have the following system of equations:
<span>
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

Hey ! there
Answer:
- Simplest fraction form of 85% is <u>1</u><u>7</u><u>/</u><u>2</u><u>0</u><u> </u><u>.</u>
Step-by-step explanation:
Question says that we have to write the <u>simplest</u><u> </u><u>form </u><u>of </u><u>8</u><u>5</u><u>%</u><u> </u><u>as </u><u>it's </u><u>fraction</u><u> </u><u>.</u>
<u>Solution </u><u>:</u><u> </u><u>-</u>

We know that ,
- Percent ( % ) = <u>1</u><u>/</u><u>100</u>
So ,

or ,

Reducing the fraction by cancelling it by 5 :

We get :

Now , we can't reduce 17/20 .
- <u>Henceforth</u><u> </u><u>,</u><u> </u><u>1</u><u>7</u><u>/</u><u>2</u><u>0</u><u> </u><u>is </u><u>the </u><u>simplest</u><u> </u><u>form </u><u>of </u><u>8</u><u>5</u><u>%</u><u> </u><u>.</u>

Equilateral triangle. because all sides are equal.
Answer:the slope would be 7/3
Step-by-step explanation:
This is because you write the slope in rise over run form and use the two points provided to get 14/6 and reduce hat number down to 7/3.
