Select all ratios equivalent to 3:2.
weeeeeb [17]
So the Correct answer would be all three of them.
This includes 27:18, 12:8, and 21:14.
The math behind this includes proportions.
For instance, if you multiple 3 by 9, you get 37. You have to multiple 2 by 9 now, and you should get 18. This is how all three of the answers are correct!

I’ll fail if I don’t get this right pls help
son4ous [18]

Step-by-step explanation:

In order to find the number of solutions, we have to expand both sides out first.

3(x - 2) + 7x =  \frac{1}{2} (6x - 2)

First, expand 3(x-2), which will obtain 3x-6.

Next, expand (1/2)(6x-2), which gives 3x - 1.

The result at this point should be as shown below:

3x  - 6 + 7x = 3x - 1

Now, we would shift all x terms to the left and all number terms to the right.

3x + 7x - 3x =  - 1 + 6

After simplifying, the final equation would be:

7x = 5

This is a linear equation and it has one solution.

x =  \frac{5}{7}
