What is the answer to 5(n-7)=2(n+14) work
2 answers:
Answer:
The answer is n=21.
Step-by-step explanation:
To solve the equation for (n), start by using the distributive property on both sides of the equation. The distributive property is multiplying the sum of two or more addends by a number which will give the same result as multiplying each addend individually by the number and then adding the products together.
The equation will look like after using the distributive property. Next, add 35 to both sides of the equation, which will look like
, and then subtract (2n) from both sides of the equation, which will look like
. The next step is to simplify the equation, which will look like
, and the final answer to the equation will be
.

Answer:
B
Step-by-step explanation:
Notice that the equation shows going from a solid to an aqueous solution, which is dissolved. Entropy is essentially when a system becomes more disordered. Whenever we go from solid to liquid to gas, that's becoming more disordered because the molecules in the system are moving much more and in more random directions.
In addition, when we dissolve solids into water, that's another increase in entropy because we technically have a liquid component here and the molecules are now breaking apart.
So, the entropy here will increase.
