Can you help me with this!!!!!!!!!

a. The first variable is x and the second variable is y.

b. The equations are $x+y=12$ and $x-y=8.$

Step-by-step explanation:

Step 1:

The first step is to define the variables. The variables can be any two symbols, letters, characters, etc.

Here let the first variable be x and the let the second variable be y.

So the variables are defined as x and y.

Step 2:

The sum of the given variables is 12.

The first variable + the second variable = 12,

$x+y=12.$

The difference between the two variables is 4.

The first variable - the second variable = 4.

$x-y=4.$

Step 3:

If we add both the equations we get, $2x =16, x= 8$ and $y=4.$

x = 8 and y = 4.

Hi!

We know that there are three measures and each has a different amount of notes. To find the total we add them all up.
8+16+4=28.

There were 28 total notes played in the song.

Of the fifth grade students 15/20 went to the book fair.Of the students who went to the book fair,12/16 bought at least one book

Vaselesa [24]

Answer:

$\frac{9}{16}$

Step-by-step explanation:

Let total number of students $=x$

Students went to the book fair:

Students went to book fair $=\frac{15}{20}\times total\ number\ of\ students=\frac{15}{20}x$

Students who bought book:

$Students\ who\ bought\ book=\frac{12}{16}\times Number\ of\ students\ went\ to\ book\ fair=\frac{12}{16}\times \frac{15}{20}x=\frac{9}{16}x$

Hence $\frac{9}{16}$ of total students bought at least one book.
