Since the problem is not concerned about the order of choosing the captain, the concept used is the combination. From 8 players, 2 are to be chosen,
8C2
The numerical value of the combination is 28. Thus, the answer is letter B.
In this question, you're simplifying the inequality by solving for x.
Solve for x:
12 > -3x + 6
<em>flip the equation:</em>
-3x + 6 < 12
<em>subtract 6 from both sides</em>
-3x < 6
<em>divide both sides by -3, while also flipping the inequality</em>
x > -2
Answer:
x > -2
Answer: 
-3 times the square root of 5
=============================================
Explanation:
Let 
Replace all the root 5 terms with x and we go from
to
From here, combine like terms to get
and the last thing to do is replace the x with sqrt(5)
Meaning that,
Answer: 3.5
Step-by-step explanation:
2.10/0.6=3.5
3.5x0.6=2.10
