Answer:

You will have 48 blue streamers.

Step-by-step explanation:

This question can be solved by proportions, using rule of three.

We have that:

For 12 blue streamers, there are have 9 gold streamers. How many blue streamers are there when there are 36 gold streamers?

12 blue - 9 gold

x blue - 36 gold

Applying cross multiplication

$9x = 36*12$

Simplifying by 9

$x = 4*12 = 48$

You will have 48 blue streamers.

9. Five times a number is the same as the number added to five. What is the<br> number?

Alenkinab [10]

Let x be the number

5x = x + 5

subtract x from both sides

5x - x = 5

4x = 5

Divide both sides by 4

4x/4 = 5/4

x = 5/4

=======

Check:

5 * (5/4) = (5/4) + 5

25/4 = 1.25 + 5

6.25 = 6.25

Hope it helps . Note that I am a sixth grade student and I don’t know anything . I got help from somebody
