There are twice as many boys as girls in Ms. Sam's class.
When three new girls join her
class, she will have 24 students.
How many boys and girls were
originally in her class?

21

Step-by-step explanation: 3 new girls join the class and if you subtract 24 - 3 its 21.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
