If m = baseball cards he had yesterday, and today he got rid of 5, the expression is equal to
m - 5 = x.
As an example of what the answer is, replace m with 10.
If he had 10 baseball cards and gave away 5 today, x = 5.
The answer is m - 5 = x.
Answer:
<h2>(-36 : 4) + 9 = -36 : 4 + 9 = 0</h2>
Step-by-step explanation:
9 more than the quotient of -36 and 4.
<em>the quotient of -36 and 4 → -36 : 4 = -9</em>
<em>9 more → + 9</em>
9 more than the quotient of -36 and 4 → -36 : 4 + 9 = -9 + 9 = 0
First of all, you would make 6 1/4 into an improper fraction. This makes it 25/4, then you multiply it by 2 to get 50/8 and have common denominators. Divide that by 1/8, which would be 50. Then since each 1/8 costs 2 dollars you would multiply 50 by 2. So, the answer would be that they made 100 dollars.
Answer:
2
Step-by-step explanation:
6x+24=36
6x=36-24
6x=12
x=2
Answer:
Step-by-step explanation:
Let the probability that he gets the correct answer be m.
If he gets the answer, then either he knows it (a probability of p) or he does not know it but guesses correctly (r × 1/2). Therefore,
Let the probability that he gets the incorrect answer be n. Then, by being complementary events
This is a binomial or Bernoulli distribution since he gets the answer either correctly or incorrectly. The probability of at least 19 correct answers out of 20 is the sum of the probabilities of 19 or 20 correct answers.
