Question

In a certain town, the barometric inches of air pressure, x, on a certain day is described by two statements:
If 3 times the air pressure is increased by 2, the pressure is still less than 92 inches.
Twice the air pressure minus 39 is greater than 11 inches.
Part A: Create a compound inequality to represent the air pressure range. (3 points)

Part B: Can the air pressure in this town be 24 inches? Justify your answer by solving the inequalities in Part A. (3 points)

Part C: The average air pressure in another town is 29 inches but the actual pressure is within 4 inches of the average.

Answer 1

\[3x+2<92\]

Answer 2

i hate to say this but i'm not good with this type of math sorry

Answer 3

:(

Answer 6

Hello mate

Answer 7

Hello!!!!!

Answer 8

I did the first equation, not sure if im correct

Answer 9

U r

Answer 10

Try to do the other

Answer 11

what was the first equation

Answer 12

\[2x-39>11\]

Answer 13

Correct for the 2nd

Answer 14

Now. Let's solve part A

Answer 15

what's a compound equality

Answer 16

Solve for x for each inequality
And then the range is the answer of x of each inequality
Like the following
X> 2 or x< 9

Answer 17

So did u solve them inequalities?

Answer 18

yeah working on it

Answer 19

1 min

Answer 20

we have as long as you need

Answer 21

x = 30 on first equation

Answer 22

x = 25 on 2nd

Answer 23

the signs are left the same way

Answer 24

\[x <30\]

Answer 25

\[x >25\]

Answer 26

3x + 2 < 92

X< 30

The 2nd is 2x -39 > 11
X> 25

So the compound inequality is
25<X<30

Answer 27

Make sense?

Answer 28

yes yes

Answer 29

Good
Now that was A
Let's move to B shall we

Answer 30

In B they say can x= 24?
Would that make the inequality correct?

Answer 31

Will.H you should become a qualified helper

Answer 32

Thank you :)

Answer 33

I know right..... Part B?

Answer 34

u r welcome Will.H

Answer 35

you should become honorary professer of mathamatics

Answer 36

lets get back on topic now alright

Answer 37

Part B no because we get an outcomme to 25

Answer 38

Lol Thanks guys
So part B
The compound inequality we have is 25<X<30
If we say x= 24 would that be in the range of the right values that the inequality support.
Let's see
25< 24 (24 is not bigger than 25)
24<30 (24 is indeed less thab 30)
However since one of the parts is incorrect then x= 24 cannot be within the range.

Answer 39

Make sense?

Answer 40

i so was right

Answer 41

What

Answer 42

not to me but then again i was never very good with math i'm more of a chemistry king of guy

Answer 43

i meant to say kind of guy not king of guy

Answer 44

part c

Answer 45

yes makes sense

Answer 46

Do u get part B before moving to C?

Answer 47

Okay

Answer 48

yes i did get it

Answer 49

So they gave us data. But I don't know what they want to find out

Answer 50

well i got to go and help someone else before 9:50 if i'm not here for 45 min. after i'll be back at 1:15 in the afternoon or at this time tomarrow

Answer 51

Alright mate. See u later

Answer 52

The average air pressure in another town is 29 inches but the actual pressure is within 4 inches of the average. Write and solve an inequality to find the range of air pressure in this town.

Answer 53

i can't belive this i was going to fan rising but he most of justed blocked me

Answer 54

O lololol

Answer 55

So anyway for C here's what I got
4<29<4
The average pressure is 29 but the real one could be within 4 of the average that means less than or bigger than 29 by 4

So we wrote inequality above idk if they are trying to link this inequality by the one we made in A
But the inequality I wrote above represent what they said

Answer 56

Will.H

Answer 57

how do i solve that

Answer 58

This is the inequality For C
X> 4 or X<4 and x= 29
So as compound inequality that would be
4<X<4
And they said x= 29 so
4<29<4
Make sense?

Answer 59

oooo

Answer 60

No no

Answer 61

i've got 1 last one

Answer 62

They are trying to link that for the one in part A hang on I'll explain

Answer 63

alright

Answer 64

X-4< 29
The other is
X+ 4>29
Solve for x for each

Answer 65

\[x <33\]

Answer 66

And you'll get ur answer
Such that
X<33
Or X>25
So the compound inequality be
25<X<33
Make sense?

Answer 67

yes

Answer 68

That's all mate
Hope that helps

Answer 69

okay it did actually lol alot... i really thank you

Answer 70

i have 1 mire

Answer 71

more

Answer 72

You welcome. Post it up in a new quotation
I'll go for 5 mins and then be back

Answer 73

alright

Answer 74

wait wait

Answer 75

nevermind

Answer 76
