The length of the blue ribbon is two-thirds the length of the red ribbon. Write an equation to find the length r of the red ribbon.

The equation to find the length r of the red ribbon is:

Solution:

Let "b" be the length of blue ribbon

Let "r" be the length of red ribbon

To find: equation for length r of the red ribbon.

The length of the blue ribbon is two - thirds the length of the red ribbon

Which means,

Therefore,

Thus the equation to find the length r of the red ribbon is found

an equation to find the length r of the red ribbon is , where b is the length of blue ribbon.

Step-by-step explanation:

We have , The length of the blue ribbon is two-thirds the length of the red ribbon. Let length of red ribbon is r cm , than length of blue ribbon is  two-thirds the length of the red ribbon i.e. .

Length of red ribbon = r cm

Length of blue ribbon = b = cm

⇒ Length of blue ribbon = b = cm

⇒ b =

⇒

Therefore, an equation to find the length r of the red ribbon is , where b is the length of blue ribbon.

a negative exponent is translated as follows:

so, we have

yo answer should be 6 if im not mistaken
