Question

HELP FOR A MEDAL AND A FAN

Answer 1

n a certain town, the inches of rainfall, x, on a certain day is described by two statements:
If 3 times the rainfall is increased by 2, the rainfall is still less than 26 inches.
5 plus twice the rainfall is greater than 11 inches.


Part A: Create a compound inequality to represent the rainfall range. (3 points)

Part B: Can the rainfall in this town be 4 inches? Justify your answer by solving the inequalities in Part A. (3 points)

Part C: The average rainfall in another town is 5 inches, but the actual rainfall is within 4 inches of the average. Write and solve an inequality to find the range of rainfall height in this town. (4 points)

Answer 2

Solve the equations:
3x+2 < 26 ------(i)
5+2x > 11 -------(ii)

Answer 3

what part are they for??

Answer 4

x<8
x>3

Answer 5

These are the equations you make from the question.
For (A) , Solve both the equations and you will have your range.
For (B) Solve the first equation.

Answer 6

ok, what about C

Answer 7

Let me take a look.

Answer 8

thanks your amazing

Answer 9

anything???

Answer 10

Does part c has anything to do with the main question or is it a separate one ?

Answer 11

there all on the same question
i guess

Answer 12

looks separate but they just want you do get the same idea i guess

Answer 13

it says the actual rainfall is within four inches of the average which means it is greater than 1 (or maybe 0.5) and smaller than 4 , since 5 is the average. We just have to somehow relate all this.

Answer 14

omg i figured it out
|5-x|<or equal to 4

Answer 15

is that it???
]

Answer 16

is 5-x is inside a "mod"

Answer 17

no it is inide a um um um i can't think of the name

Answer 18

there brackets things that make the answer positive

Answer 19

yes those are mods and I think you got the equation right. It fits the question.

Answer 20

ok so

Answer 21

yeee thank you soooooooo much

Answer 23

Solve it and it says
x is greater than equal to 1

Answer 24

what

Answer 25

yes that is your range between 1 and 4

Answer 26

wait where does it say that''''''''''''''''''''''''''''''

Answer 27

ohhhh

Answer 28

So did you get it ?

Answer 29

do you think that A is wrong then?

Answer 30

No not part (a).
|5-x| <= 4
x >= 1

Answer 41

try now

Answer 42

nope

Answer 43

=\-,-

Answer 44

-.-

Answer 45

i think they want me to use the || like i did on the other ones?

Answer 46

Off course it will be inside mod. Rainfall in minus is absurd.

Answer 47

???

Answer 48

so what is a and b then

Answer 49

Rainfall value cannot be in minus. That is why you use mod on them.

Answer 50

ok so a is.....

Answer 51

between 3 and 8

Answer 52

no the equation whats the equation

Answer 53

I think you and I are talking about two different things here.
Wait let me clarify.

Answer 54

ok

Answer 55

is this correct??
Part A: 3x+2 < 26
x<8
5+2x > 11
x>3

Part B: yes it can

Part C: |5-x|<4 the range is 1-4

Answer 56

For Part(A) You solve the two equations that I wrote. You answered x<8 and x>3.
So the range of rainfall is between 3 and 8 inches.

For part (b) It can be four inches because the range is between 3 and 8 inches.
For Part (C) You already gave the equation |5-x| <= 4.
Solve it and you have your answer.

Answer 57

Yes that is right.

Answer 58

ok thank you so much I gave you a medal and i would hug u if u were here thank you soooooooooooo much

Answer 59

You are welcome. :)

Answer 60

bye thank you!!
