If 1/x + 1/3x = 5, what is the value of 3x/4

The answer is 1/5

Step-by-step explanation:

First, you make it into 1 fraction by making the denorminator same:

1/x + 1/3x = 5

(3+1)/3x = 5

4/3x = 5

It is given that we need to find the valus of 3x/4. We can see that the previous working, 4/3x=5 is almost similar to the question so you can flip upside down the working to make it into 3x/4:

4/3x = 5

3x/4 = 1/5

OR

You can use 1 to divide both side to make it more understandable:

4/3x = 5

1 ÷ (4/3x) = 1 ÷ 5

3x/4 = 1/5

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
