: a box contains 24 red cubes and x blue cubes. the probibility of pulling out a blue is 1/3.
a. how many cubes are there all together?
b.write an expression from part (a)for the probibilty of pulling out a blue cube.
c.write and solve an equation with two equal ratios to find the number of blue cubes
d.explain why your anwer makes sense This question is from textbook cpm algerbra
You can put this solution on YOUR website! a)
1/3 of the cubes have to be blue.
x/(x+24)=1/3
3x=x+24 Multiply each side by 3(x+24)
2x=24
x=12
12+24=36 cubes altogether.
.
b)
1/3 probability of pulling out a blue cube
.
Now that you understand the answer you can do the last 2 parts.
