The -18°C temperature as the freezing point of maple syrup means that the temperature at which maple syrup changes from liquid to solid (that is, freezes) is 18° below the freezing point of water.

Step-by-step explanation:

It is explained that the freezing point of water is used as the standard or reference point to calibrate the Celsius scale.

The scientists use 0°C to represent the freezing point of water and subsequently use positive numbers to indicate temperatures above the freezing point of water and negative numbers to indicate temperatures lower than the freezing point of water.

So, a temperature/freezing point of -18°C simply means that the temperature/freezing point is 18° lower than the freezing point of water.

Hope this Helps!!!

Josiah has 3 packs of toy animals. eac pack has the same number of animals. josiah gives 6 animals to his sister stephanie. then

Nataliya [291]

To determine the number of animals in each pack, we need to understand each statement in the problem since these are key to obtaining the correct answer.

number of packs = 3
number of animals given to sister = 6
number of animals left = 9
total number of animals = 6+9 = 15

It is said the in each pack there is an equal number of animals. Therefore,

Number of animals per pack = 15 / 3 = 5 animals
