The problem can be represented using an equation:
2.4x + 5.28 = 7.32
Where x is the price for the grapes.
To solve for x, we can start by isolating the variable on one side of the equation:
2.4x = 2.04
Then we can divide both sides by 2.4:
x = 0.85
Therefore, the price for the grapes was $0.85 per pound.

The table shows the relationship y = kx what is the Contant of proportionality k
We need more information to determine the constant of proportionality, k.
If the table has numerical values for both x and y, we can find k by dividing any y-value by its corresponding x-value. For example, if the table looks like this:
| x | y |
|---|---|
| 1 | 4 |
| 2 | 8 |
| 3 | 12|
We can see that when x=1, y=4. So:
k = y/x = 4/1 = 4
And we can check that this holds for the other values of x and y as well:
k = y/x = 8/2 = 4
k = y/x = 12/3 = 4
So the constant of proportionality for this table is k=4.
However, if the table only provides the relationship y=kx, without any numerical values for x or y, we cannot determine the value of k.

so is it 1/3
I'm sorry, but without additional information or a specific table or equation, I cannot determine if the constant of proportionality for y=kx is 1/3.

To determine the constant of proportionality, k, we need to find the ratio of any y-value to its corresponding x-value. Let's choose the first pair of values, where x=12 and y=60:
k = y/x
k = 60/12
k = 5
So the constant of proportionality k is 5.
We can check that this holds for the other pairs of values:
For x=9 and y=45:
k = y/x
k = 45/9
k = 5
For x=6 and y=30:
k = y/x
k = 30/6
k = 5
For x=3 and y=16:
k = y/x
k = 16/3
k = 5
So the constant of proportionality for this table y=kx is k=5.
k = y/x
k = 60/12
k = 5
So the constant of proportionality k is 5.
We can check that this holds for the other pairs of values:
For x=9 and y=45:
k = y/x
k = 45/9
k = 5
For x=6 and y=30:
k = y/x
k = 30/6
k = 5
For x=3 and y=16:
k = y/x
k = 16/3
k = 5
So the constant of proportionality for this table y=kx is k=5.
the product of a number x and 0.28 is 13.44. which equation matches this statement?
1. 0.28 divided x =13.44. 2. 13.44.x = 0.28 3. 0.28x = 13.44 4. x divided 13.44 =0.28
1. 0.28 divided x =13.44. 2. 13.44.x = 0.28 3. 0.28x = 13.44 4. x divided 13.44 =0.28
The equation that matches the statement "the product of a number x and 0.28 is 13.44" is:
3. 0.28x = 13.44
This equation can be solved to find the value of x by dividing both sides by 0.28:
x = 13.44 / 0.28
x ≈ 48
So the number x that satisfies the statement is approximately 48.
3. 0.28x = 13.44
This equation can be solved to find the value of x by dividing both sides by 0.28:
x = 13.44 / 0.28
x ≈ 48
So the number x that satisfies the statement is approximately 48.
