Solve: 12 - 2x = -2(y - x)
Steps:
1. Expand -2(y - x): -2y + 2x
12 - 2x = -2y + 2x
2. Then subtract 12 from both sides
12 - 12 - 2x = -2y + 2x - 12
3. Simplify,
-2x = -2y + 2x - 12
4. Then, subtract 2x from both sides
-2x - 2x = -2y + 2x - 2x - 12
5. Simplify,
-4x = -2y - 12
6. Then, divide both sides by -4
-4x/-4 = -2y/-4 - 12/-4
7. Simplify,
x = 1/2y + 3 <======= <em>Answer</em>

Answer:
179/1.60934 miles then divide to get the whole number/ decimal.
Step-by-step explanation:
A quick search tells me there are 1.60934 km in 1 mile.
To convert from one unit to another there is a super simple method. Set up a fraction with the two values, so in this case 1/1.60934 or 1.60934/1. Which do you use? well it depends which you are tryng to convert.
1.60934/1 has the units km/miles so since miles is on the bottom we would use it to convert miles. That's hat you have to look at, what is in the denominator. Since we are converting 179 km we want km on the bottom.
So we use 1/1.60934 instead because the units are miles/km. now you just multiply the 179 by the fraction. so the answer is 179/1.60934 miles.
Now it says we need a whole number of decimal, can you handle the division?
The value of x is 2 because the centroid of the triangle divides each median in the ratio of 2:1 option (C) is correct.
<h3>What is the triangle?</h3>
The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
RQ = 3x+2 ,QN = 2x and SM=3x
In the figure, the TM, Rn, and SL are medians of the triangle SRT and Q is the centroid.
The centroid of the triangle divides each median in the ratio 2:1
RQ/QN = 2/1
(3x+2)/2x = 2/1
After solving:
3x + 2 = 4x
x = 2
Thus, the value of x is 2 because the centroid of the triangle divides each median in the ratio of 2:1 option (C) is correct.
