Answer:
Muchos de los problemas de las ciencias, economía, finanzas, medicina y otros numerosos campos se pueden traducir a problemas de álgebra. Ésta es una razón por la
que el álgebra es tan útil. En esta sección usamos las ecuaciones como modelos
matemáticos para resolver problemas de la vida cotidiana.
Criterios para modelar con ecuaciones
Se aplican los siguientes criterios para plantear ecuaciones que modelen situaciones
formuladas en palabras. Para mostrar la manera en que los criterios pueden ayudar a
plantear las ecuaciones, anotamos al margen cuándo funciona cada ejemplo de esta

Step-by-step explanation:
Answer:
It will take a total of twenty minutes
Step-by-step explanation:
if it cools from 200 to 195 in five minutes then times two is twenty which means it's cooled to 190.
180 is twenty less then 200 so if it takes ten minutes to cool down by ten then multiply this by two and you get 180 and know it's cooled by twenty minutes
Items that are denser than water sink and items that are less dense than water float
When there is one soda, there is 25 cents, and when there are 3 sodas, there are 75 cents included in the total. So, it's safe to assume that the soda has a minimum of 25 cents each.Then, there are the same amount of donuts in both parts. So, the donuts will take up the same amount of money in both. If you can find how much those donuts are worth, you can find how much the sodas are worth, plus the 25 cents, for each.
If the donuts are worth $1 each, then take away $2 from each total.
You'll get 6.75 for the first, and 2.25 for the second.
From reasoning, you can get that each soda is equal to $2.25 and each donut is equal to $1.
There are different ways to do this, but the way I did it is simply the way my brain works.
