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 = (F - 32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car.

Answer 1

1) -30 > (F - 32) > 130; -22 > F > 266
2) -30 < (F - 32) < 130; -22 < F < 266
3) -30 < (F - 32); -22 < F
4) (F - 32) < 130; F < 266

Answer 3

your C= is missing a part

Answer 4

5/9

Answer 5

9/5 sounds familiar ... 5/9? sooo close

Answer 6

its \[c= \frac{ 5 }{ 9 } \left( 5 -32\right)\]

Answer 7

-30°C < temp < 130°C

-30 < 5(F-32)/9 < 130

multiply thru by 9/5 then add in the 32

Answer 8

f-32****

Answer 9

your options are missing parts too i believe

Answer 10

if i were to take a gander, 2 looks the most sane of them all

Answer 11

okay thank you but let me rewrite the question

Answer 12

Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car. (2 points)

Answer 13

1) -30 5/9 > (F - 32) > 130; -22 > F > 266
2) -30 5/9 < (F - 32) < 130; -22 < F < 266
3) -30 5/9 < (F - 32); -22 < F
4) 5/9 (F - 32) < 130; F < 266

Answer 14

@amistre64 better?

Answer 15

almost. i still like 2 the best,

Answer 16

1) -30 > 5/9 (F - 32) > 130; -22 > F > 266
2) -30 < 5/9 (F - 32) < 130; -22 < F < 266
3) -30 < 5/9 (F - 32); -22 < F
4) 5/9 (F - 32) < 130; F < 266

Answer 17

3 and 4 are one sided, the range is 2 sided

and -30 < 130 so the signs are off on 1

Answer 18

ohhhhhokay thank you!

Answer 19

do you have time for one more?
