5 0

Answer:

y = 5;  x = 1/5

Step-by-step explanation:

xy = 1    ----->  x = 1/y

xy^2 = 5 -----> 1/y * y^2 = 5

y^2 / y = 5

y = 5

5x = 1

x = 1/5

Hope this Helps!

A bag contains 6 red balls and blue balls. 4 balls are selected at random. find the probability of selecting 4 red balls.
masya89 [10]

Another way is to note that there are <span><span>(<span>104</span>)</span><span>(<span>104</span>)</span></span> (“10 choose 4”) ways to select 4 balls from a collection of 10. If 4 of those 10 balls are “special” in some way (in this case, “special” = “red”), then the number of ways to choose 4 special balls is <span><span>(<span>44</span>)</span><span>(<span>44</span>)</span></span>. (The factor of <span><span>(<span>60</span>)</span><span>(<span>60</span>)</span></span> is included to convey that, after choosing 4 special balls, we choose none of the 6 non-special balls.) This line of reasoning gives the second expression.

1. m – 7 &lt; 6 A) m &lt; –1 B) m &gt; 1 C) m &lt; 13 &lt;---------------------- D) m &lt; –13 2. x + 4.5 ≥ 5.5 A) x ≥ 10 B) x ≥
ikadub [295]
1) m - 7 < 6
 Add 7 to the both sides, 
m - 7 + 7 < 6 + 7
m < 13

So, Option C is your answer for this part.

2) x+4.5 ≥ 5.5
Subtract 4.5 from both sides, 
 x ≥ 1

So, Option B is your answer for this part.

3) p +12 > 9
Subtract 12 from the both sides, 
p > -3

So, Option D is your answer for this part.

4) x - 5 ≥ 9
So, Option A is your answer for this part

Hope this helps!
