Answer:
Step-by-step explanation:
Let's solve for 
in the first equation and then solve for 
in the second equation.
I will then use the following identity to get right of the parameter, 
:
(Pythagorean Identity).
Let's begin with .
Subtract 2 on both sides:
Divide both sides by -3:
Now time for the second equation, .
Subtract 1 on both sides:
Divide both sides by 4:
Now let's plug it into our Pythagorean Identity:
The correct answer is -4^5-7/4
$12.75-$11.25= $1.50, $9.75-$1.50= $8.25 his little brother should get $8.25 hope it helps

Answer: Assuming you mean that the original cost was doubled and now equals $60, the camera costed $30. Assuming the camera's price has been doubled from $60, it is $120. The wording is a bit unclear, so I'm giving you both answers.
Step-by-step explanation: To find half of the price of $60, simply divide it by 2, which gives you $30.
