The temperature of a freezer started at 18ºc. after cooling for a few hours, the freezer had a temperature of –12ºc. what is the difference between the new, colder temperature and the orithe temperature of a freezer started at 18ºc. after cooling for a few hours, the freezer had a temperature of –12ºc. what is the difference between the new, colder temperature and the original temperature?

a.–12 – 18

b.–12 – (–18)

c.18 – 12

d.18 + (–12)ginal temperature?

a.–12 – 18

Step-by-step explanation:

We have to compute the difference (the subtraction) between the new, colder temperature, which is equal to -12 °C, and the original temperature, which is equal to 18 °C, that is:

colder temperature - original temperature

Replacing with data:

-12 °C - 18 °C = -30 °C

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!
