Learning the concepts of rates, ratios, and proportions is important to those in healthcare professions because this allows them to be accurate with the dosages that is to be given to their patients. Moreover, the changes in the amount of medicine that are to be made in accordance to the need of the patient may be easily determined.
Spencer would be the correct one because it's easier to keep your variables positive when trying to solve. Therefore, in order to keep the variable positive, one would have to add 4x to both sides.
Answer:
24 feet in lenght and 15 in width
Step-by-step explanation:
The first problem, all you need to do is combine like terms then isolate the n:
4n-2n=4
~subtract 2n from 4n (2n)
2n=4
~then divide both sides of the equation by 2 to isolate the n
n=4
The second problem follows the same steps of combining like terms and isolating the variable. Here, you'll have to combine 2 like terms:
-12=2+5v+2v
~first combine the variables which is just 5v+2v which is 7v
-12=2+7v
~then subtract 2 from both sides to isolate the 7v
-14=7v
~then divide both sides by 7 to isolate the v and get your answer
-2=v
Hope that helped!
