the number of red beads Sheila has is four times as many as the number of green beads she has. There are 75 red and green beads. How many red beads does Sheila have?

75 divided by 5 = 15 so 15+15+15+15=60 she has 60 red beads and 15 green

cool ,never would have thought to do it that way:)

red + (1/4) red = 75

(5/4) red = 75

red = 60

r = 4g

r + g = 75

4g + g = 75
5g = 75
g=15
4g = 60 red.

Well I did. Understand the g

Well, let's do some math! Let's call the number of green beads "G" and the number of red beads "R." According to the problem, we know that R = 4G because the number of red beads is four times the number of green beads.

We also know that the total number of beads is 75, so we can write another equation: R + G = 75.

Now, let's use the first equation to substitute R in terms of G into the second equation: 4G + G = 75. Simplifying this equation gives us 5G = 75.

Dividing both sides by 5, we find that G = 15.

Now, let's plug this value back into the first equation to find R. Since R = 4G, R = 4 * 15 = 60.

So, Sheila has 60 red beads.

To solve this problem, let's set up a system of equations.

Let's say the number of green beads Sheila has is "x". We are given that the number of red beads she has is four times as many, so the number of red beads is 4x.

We are also given that the total number of red and green beads is 75. So, the sum of the two quantities should equal 75:

x + 4x = 75

To solve this equation, combine the like terms:

5x = 75

Next, divide both sides of the equation by 5:

5x / 5 = 75 / 5

Simplifying further we get:

x = 15

Now that we know x is 15, we can find the number of red beads by multiplying it by 4:

4x = 4 * 15 = 60

Therefore, Sheila has 60 red beads.
