Answer:

We have

n[T]=4+20-x+x+23-x

32=47-x

x=47-32

x=15

so

<u>the number of men questioned who have</u>

<u>the number of men questioned who haveall three </u><u>characteristics</u><u> </u><u>is</u><u> </u><u>1</u><u>5</u><u>.</u>

again

n[S]=6+20-x+x+24-x=50-x=50-15=35

again

we have

n[U]=n[T]+n[s]+N only [ B]

54=32+35+N only [ B]-n[T and S]

N only [ B]=54-67+20=7

<u>who are bald but</u>

<u>who are bald butnot tall a </u><u>slim</u><u> </u><u>is</u><u> </u><u>7</u><u>.</u>

(6×5) + (6×2) = 6×7

It works if you think about it like this:
5 sixes + 2 sixes = (5 + 2) sixes = 7 sixes

This is an example of the <em>distributive property</em>.
To put it simply, we're applying the same multiplication (×6) to two different things which are being added together (5+2).

Here's another example of the distributive property:
2×(3+4) = 2×3 + 2×4

What is 4.22 x 10^17 seconds

Allushta [10]

We can rewrite the given time as:

7.03x10^15 mins
1.17x10^14 hours.
4.88x10^12 days.

<h3>What is 4.22x10^17 seconds in minutes and hours?</h3>

First, remember that:

60s = 1 min

Then to write that amount in minutes, we just need to divide by 60, so we get:

(4.22x10^17)/60 mins= 7.03x10^15 mins

Now, remember that:

1 hour = 3600s

Then to get the time in hours, we need to divide by 3600:

(4.22x10^17)/3600 h = 1.17x10^14 hours.

Similarly, you can change to any time unit that you want, for example:

1 day = 24*3600 s

Then the time in days is:

(4.22x10^17)/(24*3600) days = 4.88x10^12 days.

And so on.

Question 1: x+2 = 8 doesn't belong in the given equations.

Question 2: The possible values for y are 0,1 and 2

Step-by-step explanation:

Question: Which one doesn't belong?

We will solve each equation one by one to get which equation doesn't belong with others

So,

$x+4 = -2\\x+4-4 = -2-4\\x = -6$

$x+5 = -1\\x+5-5 = -1-5\\x = -6$

$x+2 = 8\\x+2-2 = 8-2\\x = 6$

$3-x=9\\3-x-3 = 9-3\\-x = 6\\x = -6$

Hence,

x+2 = 8 doesn't belong in the given equations.

Question 2:

Given equation is:

$x+y = 5$

It is given that the values of x will be greater than 2 and less than 6 so values of x can be 3,4 and 5

So,

$3+y = 5\\y = 5-3\\y = 2\\\\4+y = 5\\y = 5-4\\y = 1\\\\5+y = 5\\y = 5-5\\y = 0$

Hence,

The possible values for y are 0,1 and 2

So,

x+2 = 8 doesn't belong in the given equations.

The possible values for y are 0,1 and 2
