Answer:
The answer is that last one.
Step-by-step explanation:
To answer this question, we first have to set up an equation with variables.
We can use "x" to represent the cost of each bracelet.
Equation: number of bracelets bought × cost of each bracelet = total cost
Number of bracelets bought: 7
Total Cost: 49
Using this information, we can fill in the equation and solve for x.
7x = 49
To isolate x, divide both sides by 7.
x = 7
Since x equals 7, we now know that each bracelet cost $7.
Sophie factored completely. Carlos did not, because he left an extra term in the factorization that Sophie removed.
Answer:

Step-by-step explanation:
Given

Required:
Determine a pair with a proportional relationship
A proportional relationship is:

Where k is the constant of proportionality.

So, we have:


This means that for a pair to have a proportional relation, k must be -1/3.
This is true for (c).
Where:

So, we have:
