Answer:
C = 8
Step-by-step explanation:
So to get C by itself, we need to add 12 to both sides of the equation, which is the opposite of subtracting:
C - 12 = -4
C - 12 + 12 = -4 + 12
C = 8
Twenty-five percent (25%) of 20 is equal to 5. Therefore, the company is planning or targeting to sell at least 25 cars next week. We let the number of cars be x. The inequality that best represent the scenario above is,
x ≥ 25
Using the probability concept, it is found that there is a 
probability the student is a boy.
<h3>What is a probability?</h3>
- A <em>probability </em>is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, according to the two-way table found on the internet when we research the problem:
- There are 11 people who are 12, of which 4 are girls and 7 are boys.
- Hence, in total, there are 21 people, of which 13 are girls and 8 are boys.
- Then, we find that there are 10 people aged 11, of which 6 are girls and 4 are boys.
Then:
There is a probability the student is a boy.

Answer:
Option B is correct, i.e. 30 ways.
Step-by-step explanation:
Given that there are 6 runners at a competition. So it means n = 6.
It says 2 medals are awarded for first and second place. So it means r = 2.
Each medal is different, it means the order matters here. It is the case of Permutations, so we will use nPr formula.
Total number of ways = 6P2 = 6x5 = 30.
Hence, option B is correct, i.e. 30 ways.
