x + y = 53
x -y = 9 Adding both equations
2x = 62
x = 31 y = 22
The probability that both marbles will be a red color is:
6..... ⇔ number that satisfies the constraint
_____
15..... ⇔ number of outcomes
Answer:
$2.50 per movie and $6.50 per video game.
Step-by-step explanation:
The correct answer is $6.50 for each video game and $2.50 for each movie. My work:
3 x 2.50 = $7.50 and 5 x 6.50 = $32.50
32.50 + 7.50 = $40.00
12 x 2.50 = $30.00 and 2 x 6.50 = $13.00
30.00 + 13.00 = $43.00
Hope i helped you
