Be that unknown number X
Then we can write the following expression:
X + 4.7 = 8.1
<h2>X = 3.4</h2>
The pair of values below is from an inverse variation. Find the missing value. (4,14), (10,y)
1 answer:
Hi there! Not 100% percent sure if it's the same here, but it wasn't too long ago we learned about inverse relationships in Chemistry. The formula goes as follows:
x1y1 = x2y2
Now you just have to plug in the information.
4 x 14 = 10 x y2
What do you do now? You isolate the variable, y2. You do this by dividing y2 by the number it is multiplied.
Like this:
As we all know, what you do to one side you must do to the other. But before you do that, you need to multiply the 4 by the 14.
4 x 14 = 56
Now you can divide by 10.
The answer should be 5.6. Hopefully this helped!
