Question

The sum of 20 and twice Vidya's height

Answer 1

Answer:

Vidya has the height of 20/3, and the person twice Vidya's height has the height of 40/3

Step-by-step explanation:

Vidya's height and another subject, let's name him Xander, or X, has the sum of 20.

V (Vidya) + X (Xander) = 20

X = 2V

X/2 = V

Let's replace the "V" with an X!

X/2 + X = 20

Now I'm multiplying it by 2 to get rid of fractions.

X + 2X = 40

3X = 40

X = 13 1/3

Xander has the heigh of 13 1/3 or 40/3
