Let's start by defining our unknown number.

Let's call it x.


Now, Let's handle the first part of it.  3 more than five times a number.  That can be represented by the following

3+5x


Now we handle the second part, "Thirty more than twice the number"

Which can be represented by

30+2x


So, now we set them equal, since it tells us that these expressions are the same.  Then we just solve the equation

3+5x=30+2x\\\\5x=27+2x\\\\3x=27\\\\x=9


The answer is 9

Hoochie [10]

Answer:

5\leq x\leq 40

Here, x denotes the additional cookies that need to be made by Walter besides 15 cookies made by him so far

Step-by-step explanation:

Number of cookies made by Walter so far = 15

He is asked by his coach to make at least 20 cookies but no more than 55.

Let x denotes the additional cookies that need to be made by Walter besides 15 cookies made by him so far.

The inequality is 20\leq x+15\leq 55

Now solve this inequality.

20\leq x+15\leq 55\\20-15\leq x\leq 55-15\\5\leq x\leq 40

Ahat [919]

Answer:

Step-by-step explanation:

Given that there are 20 non ionized containers and 73 ionized containers

Two samples are drawn without replacement

a) the probability that the first one selected is not ionized=\frac{20}{93} =0.215

b)  the probability that the second one selected is not ionized given that the first one was ionized

= When first one was ionized we got left over as 20 and 72

Hence = \frac{20}{92} =0.217

c) If with replacement left over 20 and 73 and hence prob = 0.215 as in part a

d) the probability that both are ionized=\frac{73C2}{93C2} =0.614
