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 ribb
vladimir2022 [97]

<em><u>The equation to find the length r of the red ribbon is:</u></em>

r = \frac{3b}{2}

<em><u>Solution:</u></em>

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,

\text{Length of blue ribbon } = \frac{2}{3} \times \text{ length of the red ribbon }

Therefore,

b = \frac{2}{3} \times r\\\\3b = 2r\\\\r = \frac{3b}{2}

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

Solve 9(8 - x) = 3x.
bulgar [2K]

Hello - let's do this step by step. Show your work.

You're asking: 9(8−x)=3x.

Now, simplify both sides of the equation.

9(8−x)=3x

(9)(8)+(9)(−x)=3x (To do that, distribute)

72+−9x=3x

−9x+72=3x

Now,  subtract 3x from both sides.

−9x+72−3x=3x−3x

Simplify,

−12x+72=0

After, subtract 72 from both sides.

−12x+72−72=0−72

−12x=−72

Last thing, divide both sides by -12.

-12x/12 = -72/-12

Divide.

Therefore, you have <u>x = 6</u> as your final answer.

What if Randy needs an equal number if bowls and cups for his picnic how many packs of each will he need to buy bowls number 1 p
nata0808 [166]
In order to find this, you will need to find the LCM of 8 and 6. This would be 24. For Bowls, 6*4 is 24 and cups 8*3 is 24.
So therefore
Bowls: 4 packs of 6
Cups: 3 packs of 8
