Answer:
28 students
Step-by-step explanation:
Let x be the number of girls in the class. There were two more boys than girls in her class, then the number of boys is x + 2.
Mrs. Awesome gave each boy as many jelly beans as there were boys in the class, so each of x + 2 boys got x + 2 jelly beans, so
Number of boys = x + 2
Number of jelly beans each boy got = x + 2
Total number of jelly beans all boys got = (x + 2)(x + 2)
Mrs. Awesome gave each girl as many jelly beans as there were girls in the class, so each of x girls got x jelly beans, so
Number of girls = x
Number of jelly beans each girl got = x
Total number of jelly beans all girls got = (x)(x)
Hence,
Total number of jelly beans class got = (x + 2)(x + 2) + (x)(x)
Mrs. Awesome brought 400 jelly beans, and when she finished, she had six jelly beans left, so she gave 400 - 6 = 394 jelly beans to the calss.
So,
Number of girls cannot be negative, so x = 13, x + 2 = 15 and total number of students is 13 + 15 = 28
Hello!
This is a problem about the general solution of a differential equation.
What we can first do here is separate the variables so that we have the same variable for each side (ex. with the
term and
with the
term).
Then, we can integrate using the power rule to get rid of the differentiating terms, remember to add the constant of integration, C, to at least one side of the resulting equation.
Then here, we just solve for and we have our general solution.
We can see that answer choice D has an equivalent equation, so answer choice D is the correct answer.
Hope this helps!
