3. the total cost for 9 bracelets, including shipping was $72. the shipping charge was $9. define your variable and write an equation that models the cost of each bracelet. 4. use the equation you have written above determine the cost for each bracelet. show the algebraic steps that it takes to find the answer. provide your conclusion.

The equation that models the cost of each bracelet is . Cost of each bracelet is $7.

Step-by-step explanation:

Let the cost of each bracelet is defined by the variable x.

Cost of 9 bracelet is 9x. The shipping cost is $9. Therefore the total cost of 9 bracelets, including shipping is

The total cost for 9 bracelets, including shipping is $72.

Subtract 9 from both sides

Divide both sides by 9.

Therefore the cost of each bracelet without shipping changes is $7.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
