Question

The label on the car's antifreeze container claims to protect the car between −30°C and 130°C. To convert Celsius temperature to Fahrenheit temperature, the formula is C = 5 over 9 (F − 32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car.

Answer 1

The options are
−30 > 5 over 9 (F − 32) > 130; −22 > F > 266

−30 < 5 over 9 (F − 32) < 130; −22 < F < 266

−30 < 5 over 9 (F − 32); −22 < F

5 over 9 (F − 32) < 130; F < 266

Answer 3

@savannaxx_

Answer 4

Well...
C - F = x1.8 + 32
F - C /1.8 - 32

That's the easier way to do it

Answer 5

i really am not quite sure lol but i think the first one is the common sense answer, but i wouldnt listen to me if i were you lol

Answer 6

Okay. This is very hard. So I just solve those two equations @Firejay5

Answer 7

thanks to you too @savannaxx_

Answer 8

Well -30 is less than -22 note that

Answer 9

ok hold up, i change my mind, the first one is wrong lol

Answer 10

Lol @savannaxx_

Answer 11

Is this on a worksheet or something @kewlgeek555

Answer 12

I go to virtual school which is actually easier, but now there is this new thing in all of Florida called Common Core and it messed up all of Education. Now everything is harder and the lessons don't explain, instead of ninth graders going to pre-algebra they go straight to Algebra I and math is the subject you work the most on, making it even more frustrating.

Answer 13

Are you trying to convert Celsius into Fahrenheit

Answer 14

Nope. I know that. I am trying to see how to simplify this I think the options are above.

Answer 15

No I am asking

Answer 16

Yeah, I am not trying to convert celcius to fahrenheit. I am trying to write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car.

Answer 17

It think it's the 3rd option

Answer 18

Okay. Thanks. Are you good at inequalities?

Answer 19

some what

Answer 20

im good at inequalities but yall r just giving me a headache

Answer 21

Okay...is it okay if I put another question on here?

Answer 22

Okay, I am going to put another question @savannaxx_ and @Firejay5

A publisher claims that the average salary paid at its company is $37,500 but it could differ as much as $4500. Write and solve an absolute value inequality to determine the range of salaries at this company.

|x − 37500| ≤ 4500; The salaries range from $33,000 to $42,000

|x − 37,500| ≤ 4500; The salaries are less than $33,000 or greater than $42,000.

|x − 37500| ≥ 4500; The salaries range from $33,000 to $42,000

|x − 37,500| ≥ 4500; The salaries are less than $33,000 or greater than $42,000.

Answer 23

its the first one, because it says it could differ from $4500 so just subtract that from $37,500 and then add $4500 to it :)

Answer 24

Thanks. These are one of those tests where you get one question wrong and you get a 70 or 80.

Answer 25

i hate those, im online school too

Answer 26

I know, right! And now it is super common because of this new program in Florida. Uch.

Answer 27

thanks though.

Answer 28

lol Im on connexus in flvs. it sucks

Answer 29

and no problem :)

Answer 30

WTH is connexus? Isn't connexus from connections acadamey?

Answer 31

I think it's the first one too

Answer 32

no, its from florida virtual, it just started this year

Answer 33

Wwll, I wish you good luck. This is my fourth year, but since I am in Orange County, Florida, I go to Orange County Virtual School which is like a branch from FLVS.

Answer 34

you dont live very far from me lol. good luck to you too

Answer 35

Yay! Now I can stalk you! Lol, just kidding.
