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?

Answer:

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)

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

Answer:

x>6

Hope I helped

x>6

Hope I helped

X/24>1/4

24 is 6 times 4, so 1 times 6=6

x>6 is the answer.

24 is 6 times 4, so 1 times 6=6

x>6 is the answer.

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

2) 2x+2y+3z=3

3) x+3y+2z = 5

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

2) 2x + 2y +3z = 3

3(1)+y+(-1)=4

3+y-1=4

y=2

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