Answer 1

24 students were present and 6 students were absent.

• An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the conventional form Ax + By = C.
• Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Here, according to the given information, we are given that,

There are 30 students in a class.

Now, it is given that, $\frac{4}{5}$th of 30 students were present. This means that 24 students were present.

The number of students that were absent = 30 - 24 = 6.

Hence, 24 students were present and 6 students were absent.
