The answer is: 8 red marbles!
This is because the equation can be written out like this
Blue to red - 3:2
Now it is, blue to red - 12:x
We have to think, what is the difference from the first equation to the second. We know the number 3 times 4 = 12, so we would do the same for the red, 2 times 4=8
If this helped, give me brainliest :)

Answer:
$1.09
Step-by-step explanation:
16*0.09 = 1.44, 16 + 1.44 = 17.44 (Henry's total cost)
17*0.09 = 1.53, 17 + 1.53 = 18.53 (Ella's total cost)
To find the difference we subtract 18.53-17.44 = 1.09 and so the difference including tax is $1.09
Answer:
The amount of punch mix to use is 3/4 gallons
Step-by-step explanation:
Let
x ----> parts of water
y ---> parts of punch mix
we know that
----> equation A
That means ---> The parts of water is 8 times the parts of punch mix
If we have 6 gal of water
then
substitute in the equation A
solve for y
Simplify
therefore
The amount of punch mix to use is 3/4 gallons
