More than eighteen students in an algebra class pass the first test. this is about three-fifths of the class. how many students are in tɦɛsɛ class?
a: ʟɛss tɦaռ 30
ɮ: ʟɛss tɦaռ 25
ċ: ʍօʀɛ tɦaռ 30
ɖ: 25

Option C.

Step-by-step explanation:

More than 18 students n an algebra class pass the first test and this number is about 3/5th of the class.

Let total number of students in class = x

so 3/5th of x > 18

Or >18

Now we multiply the inequality by 5

3x > 18 × 5

3x > 90

By dividing the inequality by 3

> ⇒ x > 30

So number of students in the class are more than 30

Option C is the answer.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
