pheobe has 9 rocks. she puts the rocks into 3 boxes. Each box 1 more rock then the last. How many rocks are in each box
Svetllana [295]
Hello!

We can write this as the system of equations below. We have boxes A, B, and C.

A+B+C=9
B=A+1
C=B+1

First of all we can plug our B and C values into the first equation and solve for A.

A+A+1+A+1+1=9
3a+3=9
3a=6
a=2

Now we can plug our a value into the other equations.

B=2+1
B=3

C=3+1
C=4

Therefore, there are 2 rocks in one box, three in another, and 4 in the last.

I hope this helps!

The relationship between the input values (x) and the output values (y) is :'y is one less than a quarter of x'
sattari [20]

An equation in the form of y is y = x/4 - 1

<h3>An equation in the form y = ...</h3>

The statement is given as:

'y is one less than a quarter of x'

A quarter of x means x/4

So, we have:

y = x/4 - 1

Hence, an equation in the form of y is y = x/4 - 1

<h3>Number sentences</h3>

From the question, we have:

x = -4, -2,0, 2 and 4

Substitute these values in y = x/4 - 1

-4/4 - 1 = -2

-2/4 - 1 = -1.5

-0/4 - 1 = -1

2/4 - 1 = -0.5

4/4 - 1 = 0

The above represents the number sentences

<h3>The flow diagram</h3>

This is represented as:

x                     Computation           y

-4                    -4/4 - 1                     -2

-2                    -2/4 - 1                     -1.5

-0                    -0/4 - 1                     -1

2                      2/4 - 1                     -0.5

4                      4/4 - 1                     0

<h3>The table of values</h3>

This is represented as:

x   y

-4 -2

-2 -1.5

-0 -1

2  -0.5

4  0

<h3>Ordered pairs of numbers.</h3>

This is represented as:

(-4, -2), (-2, -1.5), (0, -1), (2, 0.5) and (4, 0)
