Answer: $9
Step-by-step explanation: If Wendy wants to own a total of 12 necklaces, that means Wendy wants to buy 9 more necklaces, since she already owns 3. We know that each necklace is a dollar.
So if Wendy buys 9 necklaces for a dollar each, then the total price will be $9 for Wendy to own a total of 12 necklaces.
( 9 x 1 = 9)

Answer:
In addition, from the response shown, using a graphical calculator brings the following benefits:
1) You can write the system of linear equations as big as you want. This is: systems 3 * 3, 4 * 4, 5 * 5.
2) The response to systems of equations greater than 2 * 2 can be complicated when you graph the solution, therefore, the graphing calculator can be much more efficient in these cases.
3) You can write the linear equations in any way. Resolving by hand you should probably rewrite the system of equations to find the solution.
Step-by-step explanation:
1) The correct answer would be -48/-6.
-48 divided by -6 equals to 8.
48 divided by -6 equals to -8.
Because a positive (8) is always bigger than a negative (-8). The second option is correct.
_____________
2) The correct answer is -6.
5 * 2 = 10.
And 4 - 10 = (-6)
