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.

−30 > (f − 32) > 130; −22 > f > 266

−30 < (f − 32) < 130; −22 < f < 266

−30 < (f − 32); −22 < f

(f − 32) < 130; f < 266

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
