Which statement answers this question: casey sells half of his video games. the next day he buys 3 more. he now has 27. how many video games did casey have at the beginning? options: (a). casey had 24 video games.( b) casey had 15 video games.( c) casey had 12 video games( d) casey had 48 video games.

D

Step-by-step explanation:

Casey has some number of video games at the beginning called x. He sells half which is 1/2 x. Then he buys 3 more so 1/2 x + 3. This is equal to his current amount which is 27. So 1/2 x + 3 = 27. Solve for x.

1/2 x + 3 = 27

1/2 x =24

x = 48

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

yeah i know the problem you need. i am taking it right now. the answer is step 3
