if 40% of the students in the class are boys , and if there are 18 girls in the class , then how many students are in the class?

1 answer:

5 0

30

60% were girls so you put this as a ratio

60/100= 18/x

You calculate x to determine the total number which would equal 30.

Answer:

(L-a)/d + 1 = n

Step-by-step explanation:

Let's isolate (n-1), and after that isolate n:

1) subtract a from both sides: L - a = (n-1)d

2) Divide both sides by d: (L-a)/d = n-1

3) Add 1 to both sides, to isolate n: (L-a)/d + 1 = n
