PLEASE HELP! WILL CHOOSE THE BRAINLIEST ANSWER!!Mark has 100 blue marbles, 34 red marbles, and 98 green marbles. After pulling out 6 blue marbles, 3 green marbles, and 1 red marble, he add's 20 pink marbles. What is the probability that he will pull out a pink marble?
Answers
The probability of Mark pulling out a pink marble is approximately 0.083 or 8.3%.
To find the probability of pulling out a pink marble, we need to know the total number of marbles Mark has after making the changes described in the problem.
Mark started with a total of 100 + 34 + 98 = 232 marbles.
After pulling out 6 blue, 3 green, and 1 red marble, he has 100 - 6 = 94 blue marbles, 34 - 1 = 33 red marbles, and 98 - 3 = 95 green marbles left. This means he has a total of 94 + 33 + 95 = 222 marbles.
When he adds 20 pink marbles, his total number of marbles becomes 222 + 20 = 242.
So the probability of pulling out a pink marble is:
Number of pink marbles / Total number of marbles = 20/242 ≈ 0.083
Therefore, the probability of Mark pulling out a pink marble is approximately 0.083 or 8.3%.

Michael bought 7 pizzas from Pizza by Alfredo and 9 pizzas from Alfredo's Pizza Cafe.
Step-by-step explanation:
Cost of Pizza at Pizza by Alfredo = $3
Cost of pizza at Alfredo's pizza cafe = $5
Total amount spent = $66
Let,
Pizzas bought from Pizza by Alfredo = x
Pizzas bought from Alfredo's Pizza Cafe = y
According to given statement;
3x+5y=66 Eqn 1
5y = 3x+24 Eqn 2
Putting value of 5y from Eqn 2 in Eqn 1;
Dividing both sides by 6
Putting x=7 in Eqn 2
Dividing both sides by 5

when you subtract a negative, you "take away" that negative from the other value. The net result of that is adding the number. So the rule is minus negative means plus positive.
-282 - (-68) =
-282 + 68 = -214
