A number, y, is equal to the difference of a larger number and 3. The same number is one-third of the sum of the larger number and 9. Which equations represent the situation?

The equations are

Step-by-step explanation:

Let the number be y and larger number be x.

A number, y, is equal to the difference of a larger number and 3.That is

y = x -3

The same number is one-third of the sum of the larger number and 9. That is

So the equations are

Equations:

Let x=the larger number

1. y=x-3
2. y=1/3(x+9)

Replace the box with a number to make blank over 24 greater than 1 over 4 a true statement

x>6
Hope I helped
X/24>1/4
24 is 6 times 4, so 1 times 6=6

3x+y+z=4
2x+2y+3z=3
X+3y+2z=5

1) 3x+y+z=4
2) 2x+2y+3z=3
3) x+3y+2z = 5

1)*2 6x + 2y + 2z = 8
2)    2x + 2y +3z  = 3

4x - z            = 5

2)*3  6x + 6y + 9z = 9
3)*2  2x + 6y + 4z = 10

4x+5z             =-1

4x+5z = -1
4x - z =5
- ________
6z = -6
z = -1

If z=-1,

4x -(-1) =5
4x = 5-1
x = 4/4
x=1

3x+y+z=4
3(1)+y+(-1)=4
3+y-1=4
y=2

So z=-1, x=1, y=2

Elsie says that the question "Do you have any siblings?" is a statistical question. Mark says that "How many siblings do you have?" is a statistical question. Who is correct?

In the given question, Mark is correct.

What is a statistical question?

A statistical question is one that can be answered by collecting data from several sources.

The question Elsie asked is a yes/no question, you can't answer the question in terms of data/numbers, but the question mark asked has to be answered in terms of data/numbers, hence it is a statistical question.
