Answer:
24
Step-by-step explanation:
75% of x = 18
75/100 * x = 18 (x = total number of students)
solving
x = 24
total number of students = 24
Checking:
75/100 * 24 = 18
Answer:
x = 2/3, -2/3

Answer:
D.
.
Step-by-step explanation:
Given:
We need to reduce
by 
Solution:
To reduce the equation means we need to subtract the one equation from other.
First we will arrange the equation n proper format we get;
⇒ equation 1
Also Arranging other equation we get;
⇒ equation 2
Now we will subtract equation 2 from equation 1 we get;

Now Applying distributive property for the sign we get;

Now Arranging the like terms we get;

Hence the reduce form of the given equation is
.
The answer to that will C and that is easy
