Which mathematical sentence most accurately expresses the information in the problem below? Crystal has 121 compact discs that s

ExtremeBDS [4]

Crystal has 121 compact discs. The total number of boxes required are 5.

<u>Solution:</u>

Given, Crystal has 121 compact discs that she wants to put into boxes.

Each of the boxes that she brought home holds 25 discs.

We have to find how many of these boxes will she need for all of her discs?

Now, we know that, number of boxes required $=\frac{\text {total number of discs}}{\text {capacity of one box}}=\frac{121}{25}=4.84=5$

Here we took 5 because 0.84 means that box with discs less than 25 still we require a box.

Hence, the total number of boxes required are 5.

Sarah made a necklace using 5 times as many blue beads as white beads. She used a total of 30 beads. How many blue beads did Sar

iogann1982 [59]

Let

x-------> the numbers of blue beads

y-------> the numbers of white beads

we know that

$x+y=30$ --------> equation $1$

$x=5y$ --------> equation $2$

Substitute equation $2$ in equation $1$

$(5y)+y=30\\ 6y=30\\ y=30/6\\ y=5$

Find the value of x

$x+y=30\\ x+5=30\\ x=30-5\\ x=25$

therefore

the answer is

the numbers of blue beads is $25$
